In lab testing of FreeBSD 6.2, I ran out of horsepower on my two test boxes (HP DL145G2 - dual core Opteron boxes) generating around 400k pps of 64byte udp frames through HP DL380G5 and HPDL385G2 boxes. CPU wise, we ran 20% lower CPU usage on the AMD processors than the Intel - this was likely due to CPU cache differences. We could have pushed them harder with a few more generator machines, but pure pps wasn't a huge issue for us and that far exceeded the packet rates we see in production (around 150k pps, but much closer to 1gigabit traffic rates). If you really have that high of a pps requirement, I'd highly recommend Intel NICs and I wouldn't bother with the PCI slots, that'll just slow you down - just get a quad card instead. I'm interested in hearing your results on this hardware - I would guess you'll be running at about 50-60% CPU load (we went with dual dual core boxes to leave a little CPU headroom, our hottest machines are now running around 40% cpu usage on FreeBSD 6.2). The 1.2.1 beta's should be of interest to you as it's on the FreeBSD 7.0 line and should see some speed improvements. --Bill --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
