I don't think that it makes sense to look at PG tuning and server tuning as two separate tasks. XFS was recently benchmarked using bonnie++ by Greg Smith, with interesting results: http://blog.2ndquadrant.com/en/2010/04/the-return-of-xfs-on-linux.html That said, my guess is that the majority of large Linux installations are using ext3 or ext4. It isn't the case that there's a favoured filesystem for Postgres. The kernel parameters that you'll want to change are sysV IPC parameters: http://www.postgresql.org/docs/current/static/kernel-resources.html If you want a guide to choosing hardware for Postgres, I can highly recommend Greg Smith's new book, "Postgresql 9 High performance". -- Regards, Peter Geoghegan -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
