Everything looks fine, save the ufs filesystem. Please realise that UFS is a pretty
naive store implementation and doesn't even try to schedule multiple reads/writes
at the same time; so if you've got some objects being read off completely different
parts of the disk (and they're not cached) then your disk performance might be
horrible - and network IO will follow that.

Just humour me and try aufs using libthr :P
