Analysis on Causes of slow web page opening in XP

After upgrading to the Windows SP2 system, this strange problem often occurs on my computer. The specific situation is that the gateway can be pinged while downloading files with Bitcomet can also work normally, however, when you open a webpage, the speed is very slow. Sometimes, the "webpage cannot be opened" page directly, and the conversation between MSN and the contact cannot be performed. For the reason, I have analyzed in an article the selection of BT clients in the Windows SP2 operating system. Now, after some time of Windows SP2 system trial and learning, we have a further understanding of the causes of abnormal network disconnection. The following is my opinion.
I. Some anti-virus software may cause abnormal network disconnection for Windows SP2 systems.

According to the conventional idea, anti-virus software has no direct causal relationship with network traffic. However, I have tested that different anti-virus software has no small impact on network traffic. The Anti-Virus software tested by the author includes Kaspersky Anti-Virus Personal5.0.142, rising star 2004, KV2004, Kingsoft drug overlord V, and Norton AntiVirus 2003. The testing environment is Windows SP2's 2180RTM operating system, and the BT client is installed as Bitcomet. After rising 2004 is installed, it will automatically restart, and then it will not be able to enter the system, so it has not been further tested. According to other anti-virus software, various network functions can run normally without the BT client. However, when you open the Bitcomet program and it displays data traffic for file downloads, the speed of opening the webpage is significantly different. Take the Sina homepage as an example. The speed of opening a webpage is sorted from fast to slow, which are Kingsoft drug overlord V, KV2004, Norton AntiVirus 2003, and Kaspersky Anti-Virus Personal5.0.142 in sequence. When the Kaspersky Anti-Virus Personal5.0.142 Anti-Virus software is installed in the test, Bitcomet cannot open many webpages as soon as it runs.

Ii. SP2 operating system default settings cause abnormal network disconnection.

In the SP2 operating system, when TCP/IP has reached its custom security limit, it will affect the number of simultaneous TCP connection requests. As a result, the network is interrupted abnormally. Experts from abroad have studied this topic. The registry key value that can be set is not found (in fact, the newly created TcpNumConnections that was first circulated on the Internet is invalid after modification). Therefore, a patch is provided to modify the TCPIP. the SYS file increases the number of connection requests by adding less than 10 semi-open connections to 50.

If you are interested, you can download from www.lvllord.de/4226fix/evid4226patch20b.exe. The TCPIP. SYS file is located in the C: WINDOWSSYSTEM32DRIVERS, C: WINDOWSSERVICEPACKFILESI386, and C: WINDOWSSYSTEM32DLLCACHE (system hidden folder) folders. Patch upgrade procedure: set C: WINDOWSSYSTEM32DRIVERSTCPIP. copy SYS to a new folder, such as c: fix, and put the patch in the folder. Run the patch and it will automatically find the TCPIP. if SYS has already been patched, it will ask you if you want to restore it (if an error occurs, you can restore it, so you can regret it ). Press the Enter key if you have not typed it. After the patch is executed, the system restarts automatically. Then press F8 to enter the safe mode and set TCPIP. copy SYS to C: WINDOWSSYSTEM32DRIVERS, C: WINDOWSSERVICEPACKFILESI386, C: WINDOWSSYSTEM32DLLCACHE, replace the original file, and then restart. We need to remind you that the patch has no obvious effect after I try it. In addition, this patch is not an authentic system patch from Microsoft. Please try it out with caution.

It can be seen that in the SP2 operating system, the network is sometimes interrupted abnormally, which is caused by some reasons of the operating system itself, as well as factors arising from the running-in process between the application software and the operating system. I believe that, after a period of expiration, the abnormal network Disconnection will certainly be solved through the joint efforts of the operating system and application software developers.
