Download speed issues with apache

Post by joshtrav »

I have searched all over the web to try to resolve this.

My current dilemma is that windows 2003 + apache 2.2 is throttling my clients download speed significantly.

I am thinking of altering my registry, more specifically DefaultReceiveWindow & DefaultSendWindow. I am unsure of what the appropriate setting for these would be however.

I have read that:
DefaultReceiveWindow = multiply your ISPs download caps in kilobytes by 1024 then divide by 8
DefaultSendWindow = multiply your ISPs upload caps in kilobytes by 1024 then devide by 8

Does this sound kosher? I am at my wits end trying to solve this.

I looked into this previously here and was unfortunately not able to find a solution: http://www.nfoservers.com/forums/viewto ... =44&t=5112. I tried just about everything I could think of. IIS works fine -- it's just Apache.

I noticed that. I am just so unfamiliar with IIS.

I will let you know how this turns out, worst case it is not help.

This was my fix by importing this into the registry.


Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\AFD\Parameters]
"DefaultSendWindow"=dword:0000ffff
"DefaultReceiveWindow"=dword:00065535

Confirming this as well. We went from download speeds capping around 120k to 550-750k pulls. Much better, and thanks for the reply squirrelof09.
