I think the general conclusion was that the Linux side looked like it
was doing the right thing and it was the Windows side or the upstream
ISP that was causing the problem. During this latest test, a different
ISP was used just to make sure (Earthlink) and came up with the same
Unfortunatly, the number of users who reported having this problem are
too great for me to ignore and I'd imagine anyone running a Web server
would have the exact same problems with Win98 clients dialed up over PPP
My best guess is that the problem lies with the size of the packets
themselves as the 2.4.0 trace shows the Windows side choaking on the 536
byte packets repeatedly and small writes going through while the 2.2.16
trace shows really only smaller writes. It was mentioned before that
2.2.x packetizes write calls, so this might make sense.
Of course, it's just a guess.
