Any idea what fixed it?

Actually, I'm not sure it's actually got fixed. At least I don't see
anything obvious in SVN history for sys/boot/zfs/zfs.c since ZVSv28
commit. I've got gptzfsboot built about 4-6 weeks back and at that
time it was as slow as it ever was probing drives in an 8-drive raidz
pool.
