SubjectRe: Poor TCP Performance 2.4.0-10 <-> Win98 SE PPP
   Date: Tue, 7 Nov 2000 08:03:42 +0100
From: Andi Kleen <>

It looks very like to me like a poster child for the non timestamp
RTT update problem I just described on netdev. Linux always
retransmits too early and there is never a better RTT estimate
which could fix it.

I thought so too, _BUT_ see my analysis of the Linux side vs.
Win98 side logs, they don't match up and therefore something
is mangling the packets in the middle. The TCP sequence numbers are
being changed!

Also, if your theory were true then 2.2.x would be affected
by it as well.
