Windows XP opens the webpage slower. Reason

After upgrading to WindowsSP2 system, my computer often has this strange problem. The specific situation is: the gateway can PING通 when surfing the Internet, and downloading files with Bitcomet can also be normal, but in The speed of opening a webpage is extremely slow. Sometimes the "Cannot open webpage" page appears directly, and the conversation between MSN and the contact cannot be performed. For the reason, the author once analyzed in an article that the WindowsSP2 operating system has a certain emphasis on the selection of BT clients. Now, after a period of trial and study of the Windows SP2 system, there is a further understanding of the causes of such abnormal network outages. The author below talks about the views.

First, some anti-virus software can cause abnormal network interruption of Windows SP2 system.

As a general rule, anti-virus software has no direct causal relationship with network traffic. However, after testing by the author, different anti-virus software has a significant impact on the network traffic. The anti-virus software tested by the author includes Kaspersky Anti-Virus Personal 5.0.142, Rising 2004, KV2004, Kingsoft Internet Security V, and Norton AntiVirus 2003. The test environment is Windows 2200's 2180RTM operating system, and the BT client is installed as Bitcomet. The Rising 2004 automatically restarts after installation, and then can't enter the system, so there is no further testing. From the perspective of several other anti-virus software, various network functions can run normally without hanging the BT client. But when you open the Bitcomet program, after you display the data stream for file download, there is a clear difference in the speed of opening the web page. Take the Sina homepage as an example, the speed of opening webpages is from fast to slow, followed by Kingsoft Internet Security V, KV2004, Norton AntiVirus 2003, Kaspersky Anti-Virus Personal 5.0.142. Among them, when testing with KASPersky Anti-Virus Personal 5.0.142 anti-virus software, Bitcomet can't open many web pages.

Second, the SP2 operating system default settings cause the network to be abnormally interrupted.

In the SP2 operating system, when TCP/IP has reached its custom security limit, it will affect the number of TCP simultaneous connection requests. As a result, the network is abnormally interrupted. Experts from abroad have specifically studied this. Since there is no registry key that can be set (in fact, the newly created TcpNumConnections that were originally streamed on the Internet is invalid after modification), a patch was created to modify the TCPIP.SYS file by increasing the number of connections that are less than 10 and a half open. Up to 50 to increase the number of connection requests.

. The file TCPIP.SYS is located in the three folders C:WINDOWSSYSTEM32DRIVERS, C:WINDOWSSERVICEPACKFILESI386, and C:WINDOWSSYSTEM32DLLCACHE (system hidden folder). Patch upgrade actual operation steps: Copy C:WINDOWSSYSTEM32DRIVERSTCPIP.SYS to a new folder, such as c:fix, put the patch into the folder, run the patch, he will automatically find TCPIP.SYS patch, if you have already played It will ask you if you want to restore it (you can restore it if you make a mistake, so that you can regret it). Press the Enter button if you haven't played it. After the patch is executed, the system automatically restarts, then press F8 to enter the safe mode, copy TCPIP.SYS to C:WINDOWSSYSTEM32DRIVERS, C:WINDOWSSERVICEPACKFILESI386, C:WindowsSYSTEM32DLLCACHE, replace the original file and restart. Need to remind everyone: I tried the patch, I feel that there is no obvious effect. In addition, this patch is not an authentic system patch from Microsoft. Please try it carefully.

It can be seen that under the SP2 operating system, the network sometimes breaks abnormally, which is caused by some reasons of the operating system itself, as well as the factors generated by the application software and the operating system during the running-in process. The author believes that after a period of running-in, through the joint efforts of the developers of the operating system and application software, the situation of abnormal network interruption will definitely be resolved.
