Are you just trying to measure ZFS's read performance here?
That is what I started looking at. We scrounged around
and found a set of 300GB drives to replace the old ones we
started with. Comparing these new drives to the old ones:
Old 36GB drives:
| # time mkfile -v 1g zeros-1g
| zeros-1g 1073741824 bytes
|
| real 2m31.991s
| user 0m0.007s
| sys 0m0.923s
Newer 300GB drives:
| # time mkfile -v 1g zeros-1g
| zeros-1g 1073741824 bytes
|
| real 0m8.425s
| user 0m0.010s
| sys 0m1.809s
At this point I am pretty happy.
I am wondering if there is something other than capacity
and seek time which has changed between the drives. Would a
different scsi command set or features have this dramatic a
difference?
thanks!,
harley.
