Sorry to cut in - So far we've found kernel 3.18 to be excellent for postgres 9.3 performance (pgbench + our own queries run much faster than with the 2.6.32-504 centos 6 kernel, and we haven't encountered random stalls or slowness). We use elrepo to get prebuilt rpms of the latest mainline stable kernel (kernel-ml). http://elrepo.org/tiki/kernel-ml Graeme Bell -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
