They seem to claim up to 70% speed gain. Did anyone proved it, tested it - with PostgreSQL in particular ?
RedHat's RHEL5 kernel is 2.6.18 with a bunch of backported features. Oracle just yanks that out and puts a closer to stock 2.6.32 based kernel in there instead. Basically the speed gain is for people who don't want to update their whole distribution, because of nonsense like "SAP etc. is only supported on RHEL5 based platforms" I think, but need the better high-speed hardware support of a newer kernel. Of course a several year newer kernel runs much faster on latest generation hardware.
