> Which arch?

amd64 and i386

> How much memory?

4g in all cases but one.  that is 1g

> What are your loader.conf settings?

on the worst one, which runs zfs

# grep -v ^# /boot/loader.conf*
/boot/loader.conf.local:loader_logo=beastie
/boot/loader.conf.local:console="comconsole vidconsole"
/boot/loader.conf.local:comconsole_speed=9600
/boot/loader.conf.local:vfs.zfs.prefetch_disable=1
/boot/loader.conf.local:zfs_load=YES
/boot/loader.conf.local:vfs.zfs.prefetch_disable=1
/boot/loader.conf.local:geom_mirror_load=YES
/boot/loader.conf.local:kern.maxvnodes=50000

on another which has gmirror, not zfs

# grep -v ^# /boot/loader.conf*
/boot/loader.conf.local:loader_logo=beastie
/boot/loader.conf.local:console="comconsole vidconsole"
/boot/loader.conf.local:comconsole_speed="9600"
/boot/loader.conf.local:vm.pmap.pg_ps_enabled=1
/boot/loader.conf.local:geom_mirror_load=YES
