Today I made some benchmarks using Tatsuo's scripts to test the
performance of ext2 vs ext3 vs software RAID5. Attached is the gnuplot
output. Note that the RAID5 setup has the WAL in another partition
with RAID1 and both are spread across three SCSI disks. The machine is
a dual pentium III 1 Ghz with 2Gb in RAM running RedHat 7.2 and
PostgreSQL 7.2.
