That is one I'd like to try, and I'd be interested in the figures for both on the same hardware for each node you are testing against. (DONT do a dumb two host many connection test its got no value as the packet patterns will not resemble real traffic and you won't be accurately assessing issues like L2 cache footprint of arp table lookups. You need to model a real network with say 300-500 hosts off mixed subnets and on mixed traffic timers to generate useful stats for say WWW network performance. >competency in benchmarking.

Well the last time I looked the VM works rather nicely now, it certainly seems to work rather well (unlike 1.2). It also passes the portability test in running on machines with 32 and 64bit architectures, as well as both physical and various virtual caches, while I'm dubious the FreeBSD vm subsystem will actually run well on a 64bit architecture - perhaps the NetBSD folk can answer why they use the Mach VM layer not yours ?
