Does anybody have any rough figures for what kind of load (both
bytes/s total throughput and packets/s) a more or less vanilla x86
running a free OS can handle today?  The last time I looked at this --
several years ago -- I seemed to top out at somewhere close to 200
Mb/s total throughput; I figured I could safely count on 100 Mb/s.
That is consistent with a 32-bit PCI bus running at 33 MHz: raw
capacity is 1 Gb/s, but each bit takes two trips over the bus, so
that's 500 Mb/s, but then there's substantial bus overhead
(contention, burst setup overhead, etc.).

Hardly vanilla x86, but in between PCs and <insert favorite
router mfg here> one has CompactPCI and cPSB.  A quick Google
search will give more info.
