hi, Thanks for all the reply.
I have found the real culprit.
Hard disk was faulty. I changed the hard disk.And now ZFS performance is much

Hi,
I did another test on both machine. And write performance on ZFS extraordinary
slow.
I did the following test on both machines
For write
time dd if=/dev/zero of=test.dbf bs=8k count=1048576
For read
time dd if=/testpool/test.dbf of=/dev/null bs=8k
