My system shows significant worse performance with ZFS - I suspect that this
is because the devices are part of a ATAPI-RAID 0 already
but here is the story - A
UFS + Softupdates -
make -j 4 buildworld - app. 24 Min (Debugging kernel)
ZFS same command but with usr/obj on ZFS
make -j 4 buildworld - app. 1h12m
The weird thing is that one sees some fantastic peak transfer numbers e.g.
up to 112MB/s - Compression is off
