This issue is already fixed in 2.4 and 2.5 :) This patch breaks tg3 build, and operation... tg3 wants a different operation than net/core/dev.c. Jeff

Claiming something and not providing tcpdumps of it is at least highly dubious. I also have a hard time to see how delayed acks should introduce user visible delays (assuming your send/receive buffer

When you claim something that fails the sanity checks of several other people and you blame Linux it is your duty to provide evidence for it. In TCP world the standard evidence is a tcpdump. tcpdumps

I remember at least one other report of such a spurious delay too. I suspect the problem is not the delayed ack algorithm as is, but the new user context TCP fast path. 2.4 added a somewhat experimen

So now that we've shown that our program does in fact exist, and does lose significant performance due to nastiness in the linux TCP implementation, what does this mean? Since this program exists in

One big problem in my opinion is how the MII monitoring is implemented. It uses ioctls that are marked for removal already in vger and hardcodes data structures in an an ugly and non portable way. I
