Generally, you should set the "size" parameter to be twice the RAM
you've got (or use bonnie++ which will auto-size it), but anyway,
something is definitely wrong with your drives, controller or the
driver. Switching schedulers won't help you, and trying different
releases will only help you if the problem is in the driver. Try asking
on the freebsd-performance @ freebsd.org list.
