SLOWWW network connection after 2.6.9 upgrade


Hoping someone here can give me some advice (related to the issue below only, thanks)

I upgraded to the unstable 2.6.9 kernel release yesterday. As soon as I reboot I noticed I am unable to browse to 90% of websites I typically can get to. I reboot to my older 2.4.25 kernel and everything is fine.

So I search (and search and search) and come to the conclusion I have this problem related to "/proc/sys/net/ipv4/tcp_default_win_scale setting". (described in: http: //lwn.net/Articles/92727).

Apparently tons of people have this slowdown problem and the fix fixes everybody.

But, hey, in the kernel I just built, this tcp_default_win_scale file does not exist and I canít seem to create it using sysctl (or any other means I know of). Iíve grepped the kernel code tree and canít find a reference to it either.

Is there some twist I can't find to creating/changing tcp_default_win_scale ?

Thanks

I had a similar problem, do you get errors saying that the pages contained no data etc? I found that ipsec was screwing with me, do you have ipsec enabled? Just a thought.

Mike.
