Обсуждение: Maximum Performance -> File System?

Hi,

ok, conclusion: lots of RAM make Postgres faster, if you adjust you
config file.
And multi-processor usage depends on your linux kernel.

But what is the best file system to use?
I'm going to run postgres on a IDE-RAID5 (hardware from 3Ware) ATA-100
system, total capacity around the 160GB, anybody had any good or bad
experience with different File systems (ext2, ext3, reiser, etc)?

Have you done any testing of RAID5 with IDE disks yet? There were reports
from people that RAID0 and RAID1 are screamingly fast with 3ware, but said
that their RAID5 had a lot to be desired.

Or FreeBSD or anything else of course.

If raw volumes were supported (like they are with some commercial
databases), then I'd say that they would be the fastest because they have
no filesystem. But I don't know if they are supported with postgres.
