His continuing rant about Apple is not, as one might think, a response to having personal experience installing Oracle on hardware running the Mac OS and running benchmarks rather than just, as you state, shooting from the lip, but alas that is not the case.

At the Northern California Oracle Users Group's Fall conference this past week I again met one of the clients I helped implement RAC on Mac: A little non-technical place called Lawrence Livermore National Laboratory.

They have what Mr. Hurley does not ... metrics ... and they are very pleased to have a stable, screaming fast cluster, that outperforms those on HPUX and Sun-Solaris by a wide margin.

Criticizing RAC on Mac without metrics is equivalent to tuning slow performance by throwing a larger SGA at the problem. It rather conveniently ignores the fact that Apple's UNIX operating system, based on FreeBSD, runs on one of the fastest chipsets IBM developed and with a bus architecture designed to move massive data sets such as movies. Attitude never trumps engineering.
