Summary FreeBSD 4.7 didnt work well with some GbE cards. Linux 2.4 works well. Iperf is not well coded. (I needed to modify) Scripts to find the best parameters (automated). Every 10 seconds SNMP polling (too fast?) Long term rrdtool records (from IU) ATM performance test by APAN Tokyo XP Next steps: IPv6, Multicast Other measurements: IPv4 / v6 ping, hops, routes Available at
