Poisson is not a glam metal band

Sean Connor reworks a load test from a constant high load to a Poisson distributed lower load, and discovers packet loss.

Since he doesn't have comments over there, I'll posit: I've seen some interesting stuff about big cache sizes causing traffic shaping in ways that degrade less well than small cache sizes, I wonder if there's some combination of hub behaviors and router caches that's causing the intermittent stuff to get de-prioritized.

Darn, I posted that the day before I leave for GenCon. Sigh.

Anwyay, I have some ideas to test (changing kernel buffer sizes, etc) that I want to test to see what might be causing the results I'm seeing.

Some more information about the setup---the two computers are hooked into the same switch, isolated to their own VLAN. While I can change the buffering on the computer side, I'll have to look into changing the buffering on the switch side of things.
