Hi

i have a Kernel 3.0.4 with zfs 0.6.0-rc5 .

Write Performance on a raidz1 whit 3 x 2TB SATA Drivs is 240MB/sek
( dd if=/dev/zero of=/datapool bs=1M count=10000 )
( compress and dedup is Off )

Read performance is 70MB/sek ?
On zpool scrub i can see 300MB/sek Read ( iostat )

Any any ideas ?
Thanks for help !
