Hi,

ah you're right. :) I forgot to symlink the pg_xlog-dir to another
partition. Now it's a bit faster than before. But not faster than
the same installation with reiserfs:

postgres@ramses:~> 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 = 178.831543 (including connections establishing)
tps = 213.931383 (excluding connections establishing)

I've tested dump's and copy's with the xfs-installation. It's
faster than before. But the transactions-query's are still slower
than the reiserfs-installation.

Are any fstab-/mount-options recommended for xfs?

best regards,
Martin
