Recently I installed a new server in my local network.

[media butcher]# uname -rsm
FreeBSD 8.0-CURRENT amd64

[media butcher]# sysctl hw.physmem
hw.physmem: 2136186880
[media butcher]# cat /boot/loader.conf
zfs_load="YES"
vm.kmem_size="1342177280"       # 1280 MB
vm.kmem_size_max="1342177280"   # 1280 MB

So, server works very nice on moderate load with
vsftpd (with sendfile enabled) - 40..70 users online.
