The FreeBSD system has 32GB of ram, dual Xeon E5620 cpus, the ZFS pool
is a 6 disk (HGST 7.2K SATA 2TB drives) raidz2 array. There's no
compression or deduplication enabled on the pool. There isn't any cache
disks setup though.
I'm starting to do some read-performance tests on the windows machine to
see if there's a problem there.
When watching the rsync processes I'm not always clear which end it's
waiting on.
