Question regarding Nagle's algorithm.

#1
I have Nagle's algorithm disabled in Windows XP in order to reduce my latency to certain games, can anyone guide me through disabling it in Windows 7? Thanks in advance. :)

Welcome to Windows7forums.. :)

I'm pretty sure this is what your looking for:

SpeedGuide.net :: Windows Vista / 2008 Tweaks

Scroll down about half way and you'll see the title Gaming Tweak - Disable Nagle's Algorithm

NOTE: This covers Windows Vista and not Win 7 specifically but it should work for Win 7 as well since Vista and 7 are very similar "under the hood".. That being said, these tweaks are to be done AT YOUR OWN RISK! ;)

Welcome to the forum this way to :)

Nagle's algorithm. Can seriously reduce latency in games . How about file transfers ? Do you disable it for normal day to day use or enable the algorithm ?

Doesn't seem to work unfortunately, I created the TcpAckFrequency Dword value and set it to 1 and it didn't do anything. Another thing worth noting is that HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters doesnt seem to exist in vista or windows 7, so setting the TcpNoDelay value doesn't work. After googling a bit more it seems that Vista needed a hotfix in order to disable nagle's algorithm, perhaps Windows 7 is the same.
