No, its much stranger. I've had problem since 2.1.9x or before on
Intel, but Alpha is fine. I've change NICs, etc. and the Intel box
still sucks and the Alpha still works.
I went back to 2.1.92 or so trying to track down the problems, alas,
before then I can't compile for some reason I forget now. I was only
checking those with significant TCP changes from the previous.
If I reboot to 2.0.x, the Intel box is fine.
I only have problems talking to some stacks, fancy stacks like recent
'95 stacks and perhaps '98 with have scaling, SACK, etc. perform very
well, not to fancy stacks like 2.0.x and NT blow goats.
A breif (possible inaccurate summary):
2.1.x Intel <-> Windows95 + IE4.01SP1 - rocks
2.1.x Intel <-> 2.1.x Alpha - sucks
2.1.x Intel <-> Windows NT 4sp3 - sucks
2.1.x Intel <-> 2.0.x Intel - sucks
2.1.x Alpha <-> Anything ? - rocks
Sucks means <= 20k/sec ov a 10Mbit switch network.
Rocks means sustains 800k or greater over the same wire.
More details and trace available upon request. I'm also happy to
provide shell access (with root and tcpdump) to people I deem
trustworthy if this will help.
