All, Domas (of Facebook/Wikipedia, MySQL geek) pointed me to this report: http://www.phoronix.com/scan.php?page=article&item=linux_perf_regressions&num=1 http://www.phoronix.com/scan.php?page=article&item=ext4_then_now&num=6 The serious problems with this appear to be (a) that Linux/Ext4 PG performance still hasn't fully recovered, and, (b) that RHEL6 is set to ship with kernel 2.6.32, which means that we'll have a whole generation of RHEL which is off-limits to PostgreSQL. Tom, any word from your coworkers on this? -- -- Josh Berkus PostgreSQL Experts Inc. http://www.pgexperts.com -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
