ZFS + NFS poor performance after restarting from 100 day uptime

Hello,
I have a system with 12 disks spread between 2 raidz1. I'm using the
native ("new") NFS to export a pool on this. This has worked very well all
along, but since a reboot, has performed horribly - unusably under load.
The system was running 9.1-rc3 and I upgraded it to 9.1-release-p1 (GENERIC
kernel) after ~110 days of running (with zero performance issues). After
rebooting from the upgrade, I'm finding the disks seem constantly slammed.
gstat reports 90-100% busy most of the day with only ~100-130 ops/s.
I didn't change any settings in /etc/sysctl.conf or /boot/loader. No ZFS
tuning, etc. I've looked at the commits between 9.1-rc3 and 9.1-release-p1
and I can't see any reason why simply upgrading it would cause this.
Since I had no issues at all with the same configuration before a reboot,
I'm reluctant to start tweaking things too much, as I didn't have to
before. As far as I can tell, the disks are fine. They're attached to a
3ware 9650 RAID card, configured to pass through the disks. The disks
are WD5000AAKS-22YGA0.
This system is used by many users for network home directories.
I should also say - the RAID controller is scheduled to do media checks
weekly. This usually takes ~10 hours. The weekend after the restart, it
took ~28 hours, but came back fine.
Does anyone have any recommendations as to where I might start looking? I
feel like this must have something to do with the controller card, as the
software changes were none that should have any impact on the performance
and the mere act of restarting the system (shutdown -r, not a true power
cycle) seemed to cause this.
For trials, I /have/ tried some common tuning (but reverted). Such as
changing the values of
vfs.zfs.vdev.max_pending, vfs.zfs.write_limit_override=1073741824. Even
for comparison, I set sync=disabled (not permanently) on that zpool.
Performance improved, but nothing significant, and I certainly don't want
to have to start tuning these if I didn't need to before.
Thanks!

at older logs, that's always been the case):
