Windows Vista: Slower Downloading or TCP/IP Auto Tuning Problem

I have install the windows vista RTM build version. I am really amazed the looks and performance of windows vista. It has detected almost all my hardware devices except sound blaster card.

After setting up network on my pc. I tried to download stuff by a means of any download manager and i noticed that download manager does not able to download fast when you generally spilt up download file into number of threads. This is beceuase of windows vista having TCP/IP Auto Tuning to ON, which is future stack implementation of TCP/IP, but sound like not working properly. To resolve this issue just open up the command prompt as administrator or type this in run window:

netsh int tcp set global autotuninglevel=disabled

After you get the OKÂ text on command prompt exit from it and reboot your computer.

Check your throughput with MySpeed (try before and after to see the difference).

Sooner or later when microsoft will resolve this issue i am sure i love my vista to be work with auto tuning on. 🙂

NOTE: this only fixes the SPI issue. It will not help gain performance under other circumstances.Â
