Five, select it and go to the next. Windows, the mouse driver to update automatically. Step 4 Reboot the PC and the upgrade is complete. Would mouse driver more appropriate, you have your mouse work in a show, why not a tool for downloading the driver, click here To view a free scan for drivers, which needs your mouse.

Why is it important that your pages load fast you might ask. The answer is simple: if your pages load, you slowly lose sales. From the perspective of a consumer, you have a split second to show activity. Your page is not completely filled, but they certainly need to see an activity at once. Consumers are impatient and have been trained by the leading websites, ad pages begin immediately. If you do not make pages load faster, most consumers go to the next page. It’s not just consumers who value speed engines, major search said it is important that pages load faster if you want them indexed. The page loads faster, more pages will be indexed. Some search engines and have said they will even downgrade your paid search marketing, if your pages load slowly. What can you do to the download page, to increase the speed? Among the techniques I used successfully to reduce the time it takes to load Web pages. Web Server Optimization SQL Server OptimizationThe first thing is to check your hard drive using PerfMon (Windows Performance Monitor). Use this option to determine if your physical disk to follow. Using Performance Monitor, select the object, physical medium. Disk Queue Length cons, the body is put in place to drive your SQL database. This indicator varies depending on the quantity, if you monitor the disk is part of a picture, but it is preferable to average less than 1 if possible to keep. See the Microsoft documentation on this subject for more information, particularly in the calculation of disk arrays. http://support. Microsoft. As usual com/kb/146005 memory check SQL. Use the right mouse button on the server in Enterprise Manager and select Properties to display the tab “Memory”. This tab allows you to give, provide as much memory as possible to SQL. The more memory you give the database the most recent can store more data, so the results back quickly. Does your server have more than 2 GB of memory? If so use these instructions to configure your server, that all available memory http://support see. Microsoft. com/kb/283037 then http://support guide. Microsoft. To configure SQL com/kb/274750 to see more memory available. To ensure that SQL uses the available memory does not use the Task Manager, because they are possibly incorrect. Instead, use Performance Monitor object process working set example sqlservr counter. Give your time server to build its cache after a reboot before checking the meter. Want to make sure that your CPU can hold. Note: This counter can be misleading. Although you may be able to systematically record high CPU usage does not mean you need a faster processor, the lack of suitable medium speed and memory, CPU utilization can be increased artificially. If CPU usage is more than 80% on average over a longer period and have already ruled out memory and hard drive as a question, you have your CPU (s update). Use System Monitor to monitor CPU usage with the object of treatment,% Processor Time counter, and applicable example, if you have more than one CPU. If your server has more than one processor and you can afford to leave, using more than one SQL, right click on the server in Enterprise Manager, select Properties, then click the CPU tab. This allows you, some or all CPUs for SQL SELECT. The bandwidth is a little more obvious, but worth mentioning. If you have a high utilization of the bandwidth of a bottleneck causing slowdowns will be maintained. bandwidth usage can control a little difficult. If you are a hosting company, they should be able to help you (to follow generally with some sort of real time that you log in), what you say with the average bandwidth and peak bandwidth. You want to make sure that a lot of bandwidth available from your hosting company, especially in the occupied part of the day. By providing your host can not these reports, you can use any hardware or software sniffer to determine the bandwidth. The key is to ensure that your connection can handle much more than usual. If you are an average of 80% utilization, you need to upgrade your connection. Now that you have checked the main hardware bottlenecks DBA Put your hat and you make sure that the indexes are updated. If you’re not an experienced DBA that the best way to manage your index, use SQL Profiler (Tools, SQL Profiler from Enterprise Manager). Create a new track and select the model SQLProfilerTuning. Make sure to take time, long enough to collect data on regular activity. In addition, if you can generate additional traffic (especially traffic causes traffic) you want to do as much as possible from this, while collecting data. When you have finished collecting data, click on Tools, Index Tuning Wizard. Use the profile you just created and make sure that the database to select the item. When you’ve finished editing in progress are proposed. You may need to run this process several times until there are no changes recommended. About how changes to your database such as adding new fields that you want to run this process again to find and implement the new recommendations. I like this process to run on a regular basis just to make sure that everything runs smoothly. As a side note, to ensure that each table in your database has a primary key. After optimizing your index run SQL Profiler to reconsider this type of activity on your SQL Server. Do you have a long-running queries that could be executed more effectively changed? Do you have any queries that are repeated several times that you use in your site cache? How updates and additions to your Web pages, you find many times to add additional applications to be made to your database. Go to your pages and whether you can combine the queries to return information from a query instead of two. If you have to do several searches to try to establish a connection to the database, then use that same connection for all applications. Thus, you can not make repeated connections to the database one by one. Create a database connection can take a lot of time and resources. So how do you help your database on the hard drives on your SQL server, if you drive to the pain high. The following configuration has worked well for me note that each partition on a separate physical disk: C: OS and SQL executablesD: File Database – RAID 5E: Login SQL FilesF: Temp DatabaseG: RAID 5 backup to disk D can be read very quickly because many readers may respond to the request. In addition, applications are expected, writing log files or temporary database. Since the player is able to read SQL data storage more efficiently to frequent requests from cache. There are a lot of questions written in the log files and SQL database temporarily, if they get another disk reduces conflict. Of course, that the use of devices at a higher speed, better throughput and a larger cache of your SQL Server support you to run faster. Web server OptimizationSince almost every page, the website of a typical Internet retailer is to establish some type of database connection, your bottleneck is likely to recover data from SQL. If this is the case, you probably will not need to do much to optimize your Web server. In general, you want to make sure that the server has enough CPU, memory and disk resources available on your Web server. Rising remember that over the cache of web pages (see Caching section of this article) is an area that you can actually increase the time the page loads. In addition, you’ll find when you try to keep your hard disk problems, some of the following: increase memory and add-caching2 When you enable logging, you move the log file locations on disc. 3 Make sure your Web pages are loaded from a partition RAID-5. Database BackupsI will not go into details of the backup database which requires a separate article. In a matter of performance you want your backup plan to run, if you have the resources available. If you’re a backup copy on another server, the backup light on a local disk first, then the backup on the LAN. This can help save full faster because it happened on the spot, when transferring the backup to another server you need with no idea how long it takes for the transfer to another server assigned. Another option is to set up a separate server that data to take into account, then you can simply use the backup server instead of the primary mirror. This reflects server can also act as backup servers if the primary server will be used. Load Balancing / Multiple ServersIf you continue to have problems after optimizing your web servers, databases, Web pages and server hardware is considering adding servers and load balancing for these servers. As each situation is different, it is impossible to enumerate all possible configurations. Here are some examples, but to do it for you in depth research to determine exactly what resources are lacking and what is the use of these resources, if you put the best decisions, such servers place, and how can load balancing important. If you currently have a single server to determine what resources are missing, probably the hard drive or memory, processor and perhaps that these resources. Usually, when multiple servers from a single server, you will be placed in a new server and you have configured your database server to new. Then I show you a configuration with three servers, which worked very well for me: Each server has SQL and IIS installed. We have a master server and two slave servers. The master server in our database to be able to write orders website to this database and our staff can process orders from this supplier database and we keep a current inventory on this server. The master server is the only server that is backed up. The two are configuration slave server so that only parts of the Web sites and databases that are necessary for the public to be replicated using our websites. Therefore, any change is made on the master server are replicated on the slave server in minutes 15. change. Because the public Web sites run the slave server in a reading “Back to the master server may write only” mode, which can handle a large number of applications very quickly. Because our master server receives written from public sites, if orders are taken, it must manage only a small amount of our transportation. As our traffic grows, we simply read one other server. In our case, we have enough links that we just share it between servers. However, if you have a website, you can still load-balanced using a round robin DNS or in extreme situations, a device such as F5 BIG-IP http://www. F5. can make us / products / BIG-IP / Smart Load Balancing current server load. Another popular method is provided for more SQL Server (which is the main obstacle) with separate data. For example, if you keep your images in SQL, you can on your own server, then they do something to connect to a server for some of your data on another server to retrieve the images. Web Page Design Java Script and CSS files, JavaScript and CSS files to the line instead of allowing your browser to cache instead of reading them at all times. Since your browser to download each file individually, you do your best all Java-Script in a single file and keep doing the same thing with pictures OptimizationOptimizing CSS image is very important in loading the page. Convert your images in PNG format. Use any HTML to scale your images, resize and optimize them before downloading. Try to keep your images to create a file size under 30K if possible. There are some advanced optimizations with embedded images that can be done, sprites and image maps, but I’m not with them, for the most experienced and in many cases, this administration can be a nightmare. In addition, there may be problems of browser compatibility. Caching Caching is a way to significantly reduce the time to load pages, especially popular for the pages. Even if your site is dynamic, you may be able to hide for four hours or less 15 minutes. You can hide the browser using the HTML header valid for all pages, select Cache. This type of caching tells the browser of visitors when it is back to exactly this page is not necessary to revisit the Web server and the page again. This will help if people were within the limits of your site and come back several times on the same page. If the page is more static, like an article page, for example, you may be able to cache it for 30 days. It’s the same person so far several sites without affecting your server go. The decline of this caching is that it only when people visit your site more than once within the cache. Another type of caching server-side page caching. This allows you to cache a page on the server instead of the browser, so the definition of time someone asks the cache site within the cache time the page is received in the cache. Caching Server from your Web server to retrieve the cache of the page (as there are enough memory resources available) that are not on the hard disk on the page or search the database means. Take the example of the first page of your site is to say a tree in the View menu to make several database queries to generate the page. If you requested this page at least once an hour there will be a heavy load on your server resources to generate. If you hide this page min for 15. They are now only provide that support resource min once every 15 allows your server to be displayed much more quickly to other requests and your page. Of all the things you can do to make your site more quickly, this may be the greatest impact. Similar to server-side page cache part is cached page. It’s a bit complicated, but you can cache parts of your page. Take the example above, this time against the criteria that we can not do everything on the page cache. In this case, we can only hide the menu menu you want, is relatively static and is a great burden on server resources and slow the delivery page. Separate DomainsSome browser opens multiple connections to download files at the same time, but have a limit on the number of download simultaneously by area. To circumvent this problem, you can file your such as images, CSS and Java Script to separate domains, so that move the browser to download multiple files simultaneously. RenderingProgressive Progressive is made when you visit a page, and you begin to see parts for the page immediately, rather than the whole page again. This process allows the user immediate feedback and they stop coming. If your site takes a second or two before making the browser, the user that there is a problem, and instead of waiting to move to another page. progressive rendering is also the illusion that the page will load faster, even if it takes the same amount of time to do a whole page. To make your next phase, you should tell your language back-end programming to put the pieces of your page because they can afford. In addition, with components such as ASP. NET GridView can not do that the gradual component, but it will make an object at once. want to ensure we view HTML, you, style sheets in the top of the page to load and Java script to the end of the page to load. This can not be done to prevent your whole page of the gradual melting. Great benefits ClassesOne ASP. NET is extremely rich with classes such as the Grid. We could devote an entire book (and I’m sure someone has) to explore the characteristics and internal workings of the grid. It is extremely flexible and easy to use. With a few simple queries, you can define a simple grid to editable. A cost of using the Grid view is that because of all the door built into a single charge. Many times this is not a problem, but you will notice an increase in display speed single-gate time you view the HTML generation and make a spreadsheet or other rudimentary way. CompressionRemove too much white space in your rendered code reduces the size of data to transmit, thereby increasing the loading of pages. In addition, configurations can be made to most web servers support GZIP (GNU compression utility) http://www. gzip. org / It is easy to reduce the size of what you transfer to half or more. This should include more CPU cycles to compress and decompress on the server through the browser, but if your server is still high CPU usage is not much affected by a slow CPU or, for that reason. On a side note, the use of this compression can cut the bandwidth of your hosting bill in half or less free of the additional bandwidth. Site Errors errors while slowing, not to mention annoying your customers. Whenever you have your code background or mistakes in web server edit additional resources away from your server. input error with error control coding is the first step. As usual, I have all the bugs in the e-mail to me if I am forced to see and recognize mentally. This allows me to assess the frequency of errors. Because I always see how they generally get on top of my list, it fixed. More time fixes for encoding in all sorts of errors are errors of participants under control, so often to avoid a total of more power. The other errors you want to keep track of the Web server errors, such as 404 (page not found). You can use the occurrence of these errors in your web server logs track. For example, if there is an old link to a page that no longer exists, rather than the Web server generates a 404 error message instead of a file (same name and location of the missing) and a match Friendly does not exist “appears, or a script to redirect to another page of your site. There are certainly many more things that you do not meet the scope of this article may explode. This a practical guide for small and medium means the Internet dealer. I hope you found this information to explore and lease review each technique before solutions in depth or expensive. Here is a Web page unloaded Time Tracker, you can use to control the speed at which you load your pages over time. This resource is unique because it uses existing Web browser on the page, including downloading and displaying CSS , JavaScript and images to. Put in place today on all your different pages, so that the data cons when you make changes to your sitemap.

If you play your Xbox 360, you sometimes want to play multiplayer games. The Xbox 360 can manage wireless connections by many Xbox 360 Controller. But if you do not have to play someone that you can connect to Xbox Live with Xbox 360 Wireless Network Adapter. The Xbox 360 Wireless Network Adapter is a device that can be connected to the Xbox 360 to connect wirelessly to the Internet. Xbox Live requires an Internet connection before you play on it. Xbox Live you can play with other players from around the world as long as you are connected to the Internet and the Xbox 360 Wireless Network Adapter is what you need – no! The Xbox 360 Wireless Network Adapter could be useful, but it has two major drawbacks. The first drawback is that it is expensive. If you can not afford to play you will not be able to Xbox Live. The second drawback is that there is a Wi-Fi is active. If you do not have a wireless connection, then you have to put up more of a wireless router, the other costs. If you do not want to spend that much, but you want a multiplayer game online with Xbox Live benefit, you must connect via a wired connection. Once you learn how to create a connection cable, the Xbox 360 Wireless Network Adapter is rendered useless. Here are the steps to connect to Xbox Live are on a cable connection: If you connect your Xbox 360 online for the same room as your modem network, then follow these steps: 1 Make sure your computer is directly connected to modem. If the modem is already connected to a router, then go to step 4. If it is connected directly to the computer and unplug the network cable to the computer and put it on the WAN port of router. Connect the second computer to the router using a different network cable. 3rd Test the connection by going to the modem and the router. The WAN LED should be green to indicate a successful connection. 4th Connect your router with the Xbox 360 with the use of a cable network. If the network cable to the Xbox 360 to connect the port I / O. 5th Turn on your Xbox 360 and Xbox LiveIf enjoy going to your Xbox 360 in line will connect from another part of your modem, then buy a Wall-Plugged Network Extender Kit and the following steps: 1 Make sure your computer is directly connected to the modem. If the modem to connect to the router, then go to step 4. If the modem is connected to the computer, unplug the network cable to the computer and connect to the WAN port of router. Connect your second computer to the router using a network cable. Check the wiring in the third turning on the modem and the router. A green light indicates a successful connection to WAN. Get a 4th Wall-Plugged grid extension and connect to the router with a cable network. Place afterwards5. Go into the room with the Xbox 360 and connect the Xbox 360 on the second Extender Wall-Plugged network with a network cable. The network cable must be connected to I / O port on your Xbox 360. Connect the Extender Wall-Plugged network for that. 6th Turn on the Xbox 360 and Xbox Live to enjoy.
