I am right now talking to someone on postgresql irc who is measuring 15k iops from x25-e and no data loss following power plug test. I am becoming increasingly suspicious that peter's results are not representative: given that 90% of bonnie++ seeks are read only, the math doesn't add up, and they contradict broadly published tests on the internet. Has anybody independently verified the results? merlin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
