[ Gigabits over Internet2 on i386 "desktop" ]

hmmm....

that page says, amongst other things, that some Serverworks III boards
that claim to interleave memory (Tyan S2567) acually doesn't; but that
the SupeRmicro 370DLE and 370DE6 boards do.

LMbench (on freeBSD 4.x) says that the Tyan S2567 has asymptotic
memory bandwidth of almost exactly 256MB/sec. On a Dell Poweredge
500sc, I get memory-throughput numbers indistinguishable from the
Tyan.

A Dell 8100 (P4, RDRAM) has almost twice the asymptotic bandwidth; but
lmbench's unrolled loops are a significant win over FreeBSD's libc bcopy,
whereas the P-/// machines   show little-to-no win here.

Anyone (Plethora Internet?) got LMbench numbers for the Supermicro boards?


NB: I'm assuming LMbench memory throughput, for LMbench's unrolled
bcopy, don't differ significantly between NetBSD and FreeBSD.
