Hi! I'm trying to meashure network throughput between two 6.2-PRERELEASE boxes, basically get maximim IP packets per second transmitted/received. Tried to use iperf from ports in UDP mode with 64 byte payload, but it calls gettimeofday() after each write and gives me about 80Kpps only for Pentium D 2.8Ghz. What alternative should I use? May be, a netgraph node? Eugene
