They do claim a lot of things, and most of the time it's along the lines "Let's take this very specific case, let's assume these rather unusual facts, let's run the benchmark on a slightly different hardware. And then we'll choose the best of the results." I've noticed that claim too (actually they claim 75%) and I've been looking for the benchmark at http://www.oracle.com/us/solutions/performance-scalability/index.html but no luck :-( I really don't expect such difference just due to switching to a different kernel. There's a space for infinite number of tweaks there (using a different default fs parameters, adding better support for the new Niagara T4 CPU not available to RedHat yet etc.). > They seem to run the same way as RHEL do, ie - you can download it for > free, but pay for repo access. (thus updates). Well, and they can change that any time they want ...
