Hi, I've installed the same installation of my reiser-fs-postgres-8.0.1 with xfs.

Now my pgbench shows the following results: [EMAIL PROTECTED]:~> pgbench -h 127.0.0.1 -p 5432 -c150 -t5 pgbench starting vacuum...end. transaction type: TPC-B (sort of) scaling factor: 1 number of clients: 150 number of transactions per client: 5 number of transactions actually processed: 750/750 tps = 133.719348 (including connections establishing) tps = 151.670315 (excluding connections establishing) With reiserfs my pgbench results are between 230-280 (excluding connections establishing) and 199-230 (including connections establishing). I'm using Suse Linux 9.3. I can't see better performance with xfs. :/ Must I enable special fstab-settings? Best regards, Martin Am Freitag, den 03.06.2005, 10:18 -0700 schrieb J.
