Recently, a lot of users have been using XP system browser to browse the page when the speed is very slow, open a Web page often need to wait a long time, everyone together to eliminate all the trouble bar, let the browser speed up.
Part of anti-virus software to WindowsSP2 system can cause network abnormal flow
According to conventional thinking, antivirus software has no direct causal relationship with network traffic. However, through the author test, different anti-virus software to network traffic impact on the network is not small. The author tested anti-virus software including Kaspersky Anti-Virus Personal5.0.142, rising 2004, KV2004, Jinshan poison pa Ⅴ, Norton AntiVirus 2003. Test environment for the WINDOWSSP2 2180RTM operating system, install the BT client as BitComet. One of the rising 2004 after installation that is automatically restarted, after the system, so no further testing. From a few other anti-virus software, in the case of no BT client, a variety of network functions can be normal operation. However, open the BitComet program, in its display with data flow for file download, the speed of open Web page has a significant difference. To open the Sina homepage For example, to open the page speed from fast to slow, in turn, Jinshan poison pa Ⅴ, KV2004, Norton AntiVirus 2003, Kaspersky Anti-Virus Personal5.0.142. In the test with Kaspersky Anti-Virus Personal5.0.142 anti-virus software, BitComet runs many web pages and simply can't open them.
Second, SP2 operating system defaults to cause network abnormal flow
In the SP2 operating system, when TCP/IP has reached its custom security limit, it will affect the number of concurrent connection requests for TCP. Thus causing the network abnormal flow. Foreign experts specialized in this research. A patch was made because the registry key that could be set was not found (in fact, the newly-created tcpnumconnections that was first circulated on the Internet was not valid). Use to modify the Tcpip.sys file to increase the number of connection requests by increasing the number of connections less than 10 half-open to 50.
Patch upgrade actual operation steps: Put C:windowssystem32driverstcpip. SYS Copy to a new folder, such as C:fix, put the patch also into the folder, run the patch, he will automatically find Tcpip.sys dozen patches, if already played, it will ask you whether to restore (out of the wrong can be restored, so you have regret medicine to eat). Press ENTER when you have not called. After the patch is executed, the system restarts automatically, and then press F8 into Safe mode to copy the Tcpip.sys to C:windowssystem32drivers, c:windowsservicepackfilesi386, C: Windowssystem32dllcache these three folders to replace the original file and then reboot. Need to remind everyone is: after I tried the patch, feel that there is no obvious effect. In addition, the patch is not Microsoft produced authentic system patches, please try carefully.
This shows that in the SP2 operating system, the network sometimes abnormal flow, both the operating system itself, there are some reasons, but also the application software and the operating system in the process of the resulting factors. I believe that after a period of running-in, through the operating system and the application of the two developers of the joint efforts of the network of abnormal flow of the situation will certainly be resolved.
