I''m sending this to zfs-discuss as I can''t replicate this problem
unless I''m doing heavy I/O on ZFS.
(Final note - this 10-disk pool is serviced by an ARC 1280ML, and

Unexpectedly poor 10-disk RAID-Z2 performance?
...'ve got a 10-disk RAID-Z2 backed by the 1.5 TB Seagate drives
everyone''s so fond of. They''ve all received a firmware upgrade (the
sane one, not the one that caused your drives to brick if the internal
event log hit the wrong number on boot).
They''re attached to an ARC-1280ML, a reasonably good SATA controller,
which has 1 GB of ECC DDR2 for caching purposes.
The machine this is all inside of is backed by an nForce 4 chipset
[hahaha], with a dual-core 1.8 GHz Opteron and 4 GB of ECC RAM
onboard. No swap is enabled.
I''m running snv_112.
I expect to get very n...
