425kpps it is for the DL385G2 (on FreeBSD 6.2)

So for a while this afternoon, I was worried that I wasn't going to be able to generate enough traffic using Click Router on a Compaq DL-145G3 to flatten (meaning, cause packets to drop/stop being forwarded, cause the CPU Interrupt Utilization was around 30%) its big brother/sister.

But if you were always wondered what it took to bring on an interrupt storm on a Compaq DL-385G2 (Opteron with 4 Cores + Quad Intel PCIe NIC) it is around 425 kpps UDP (using 60 byte packets)

Tomorrow I find out what it takes on the Intel counterpart (DL380G5)
