We ported netpipe natively... It has some nasty code in it that has
nothing to do with optimization. It's simply not written following
TPOP.
Attached is a jpg plot of the data received from netpipe. Measured
are Linux (RH7.2), FreeBSD (4.4) and Plan9, where Plan 9 is tested on
both 100baseT and Gigabit Ethernet (setup as before)...
If you need the netpipe code mail me privately and I'll send it to you
monday, but have in mind that it's rather nasty.
Some strange behaviour to be noted -- in both cases (100mbit and gige)
the test slowed down to a significant crawl when the datasize became
larger. The GigE interface showed very large variations at the end
(it is plotted with points simply because the lines were too
discouraging). Again, this could be a consequence of the port.
Both Linux and FreeBSD completed all 127(128?) iterations, but data
at the end was removed (it continued the shape of the curve without
significant change).
