I'm CCing zfs-discuss@opensolaris.org, as this doesn't look like FreeBSD-specific problem.
It looks there is a problem with block allocation(?) when we are near
quota limit. tank/foo dataset has quota set to 10m:
Without quota:
FreeBSD:
# dd if=/dev/zero of=/tank/test bs=512 count=20480
time: 0.7s
Solaris:
# dd if=/dev/zero of=/tank/test bs=512 count=20480
time: 4.5s
With quota:
FreeBSD:
# dd if=/dev/zero of=/tank/foo/test bs=512 count=20480
dd: /tank/foo/test: Disc quota exceeded
time: 306.5s
Solaris:
# dd if=/dev/zero of=/tank/foo/test bs=512 count=20480
write: Disc quota exceeded
time: 602.7s
CPU is almost entirely idle, but disk activity seems to be high.
Any ideas?
