geom mirror write performance problem

[OxY]

i removed the each disk from mirror one-by-one and ran the tests:
(when i removed one disk from the mirror the write speed was ok, 
since i added it again, then they were slow..
it was no difference which disk i did removed..)

Sco root# dd if=/dev/zero of=/dev/ad0 bs=1m count=1000
1000+0 records in
1000+0 records out
1048576000 bytes transferred in 35.962419 secs (29157549 bytes/sec)

Sco root# dd if=/dev/zero of=/dev/ad2 bs=1m count=1000
1000+0 records in
1000+0 records out
1048576000 bytes transferred in 36.575314 secs (28668954 bytes/sec)
