And one more thing. I've been passing line rate traffic for a few hours (with both netperf running the tcp_stream_script and a constant stream of UDP traffic to the discard server on the FreeBSD system) and I haven't seen a hiccup yet on the tip of RELENG_6 with jumbo frames enabled on my Dell PE2950 (one dual-core CPU, 4GB RAM). Of course I don't have any real services running on it (load average is 0.19). Any unusual settings I should be aware of? Does anyone know a simple way to drive up CPU utilization and consume large amounts of memory to try and simulate a heavily loaded system?
