This depends a lot on the hardware, the network, and lots of other things. Also, I don't think the FreeBSD kernel is optimized for high ICMP throughput. There's no reason to do that, because it's not really a real-world benchmark. You should better make some more real-world benchmarks such as transferring files. And make sure that you use comparable hardware (including identical NICs, because these can make a _huge_ difference). Also make sure that you have a switched connection in full- duplex mode. Or even better, use a direct connection with a "crossed" cable. You might also want to play with polling or other tuning parameters; please have a look at the tuning(7) manual page and the Handbook. Also make sure that you don't have any packet filters installed (IPFW, IPF, PF). Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
