I've installed the same installation of my reiser-fs-postgres-8.0.1
Now my pgbench shows the following results:
[EMAIL PROTECTED]:~> pgbench -h 127.0.0.1 -p 5432 -c150 -t5 pgbench
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
