Hi,
I did the zpool import/export performance testing on opensolaris build-134:
1). Create 100 zfs and 100 snapshots, then do zpool export/import
export takes about 5 seconds
import takes about 5 seconds
2). Create 200 zfs and 200 snapshots, then do zpool export/import
export takes about 80 seconds
import takes about 12 seconds
3). Create 300 zfs and 300 snapshots, then do zpool export/import
export takes about 110 seconds
import takes about 12 seconds
But on solaris 10 with the latest recommended patch(zfs is also V4), even with
400 zfs and 400 snapshots, the export time is still in 5 seconds, and import
time is still in 20 seconds.
It seems the zpool import/export performance was dropped so much on new
OpenSolaris build?
Regards,
Autumn Wang.
