At least under some conditions Linux tcp/ip is dead slow. If you write
packets of varying size in one direction, answering every packet with
one byte, performance is bad for sizes in the range MTU + 1 to about
2 * MTU. This can be observed over ethernet or even locally. You can
download the benchmark:

I suppose some sort of bug and would be glad if it can be fixed.
