I think your test procedure is flawed. I upped the
SIZE parameter in the makefile to 63kbytes in order
to simulate the situtation where the network buffer is
not already in the 1st level cache, which I am guessing
is the typical case. Your routines did very badly, ie
they were twice as slow as any of the other versions.
This is on a dual PPro 180 with 256kbytes 2nd level cache
per processor. It has separate 8k I and D caches for the
1st level. I compiled with -O2.
