tcpbench is a better test because it won't measure your disk i/o at the same
time
also, the realtek chip you mention has a hard limitation of around 500Mbps
on either transmit or receive, i'm not sure. this is according to luigi
rizzo's netmap testing on freebsd. try pairing it with a better chip
for testing. i'm able to get over 1Gbps single-TCP stream file xfer with
modern openbsd and fast machines and SSDs, but that's nothing notable
these days.
My interest was that (a) this was a real use case (b) the host
machines are old and slow (c) those machines in that use case
could max out the admittedly wimpy Realtek with considerable
CPU resources left over.
From the first versions introduced Realtek's advantage has been
very low price. They've never transferred at full line speed.
em is faster and I've seen 850-900 mb with it.
My point is that OpenBSD performs well with meager resources.
