I have comparable numbers for every NetBSD release from 1.2 through 1.6,
but they're really just of historical interest at this point I think.
I thought that there were a couple of very interesting regressions here.
One that really caught my eye was that our local TCP bandwidth now exceeds
our local AF_UNIX bandwidth -- that's just bizarre.
The other was the huge increase in 0-byte file create/delete latency.
But one thing to be careful with when using lmbench is that it tends to
make sampling or arithmetic errors with very large or small numbers. Is
there any chance of rerunning this with hbench-OS? It fixes some of those
