then stored on a different disk. You could think of it as a regular RAID-5
with stripe size of 32768 bytes.
PostgreSQL uses 8192 byte pages that fit evenly both into ZFS record size and
column size. Each page access requires only a single disk read. Random i/o
performance here should be 5 times that of a single disk.
think about writing 8192 byte pages randomly. and then doing linear search
over table.
For me the reliability ZFS offers is far more important than pure
performance.
Except it is on paper reliability.
