I'm in the process of adding a new filesystem to our development server
for Postgres data.  I have been using ext3fs and ext2fs for PG databases
and I haven't been impressed with the performance.
So, has anyone out there benchmarked the various Linux filesystems for
PG performance?  More information:  RH 7.3, 3 or 6 disk RAID5
(hardware).  Kernel 2.4.19.
Cheers!
Bob
