Here's a bonnie++ result for Intel showing 14k seeks: http://www.wlug.org.nz/HarddiskBenchmarks bonnie++ only writes data back 10% of the time. Why is Peter's benchmark showing only 400 seeks? Is this all attributable to write barrier? I'm not sure I'm buying that... merlin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
