Summary FreeBSD 4.7 didn’t 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 polling (too fast?) Long term records (from IU) ATM tests by APAN Tokyo XP Next steps: IPv6, Multicast Other measurements: IPv4/v6 ping, hops, routes Available at
