G5 versus the world (2715)
Good Anandtech comparison that seems to show a major weakness in OS X as a server OS. Update: read the comments. Seems to be some problems with the test. Specifically, "MySQL has a disgusting tendency to fork() at random moments, which is bad for performance essentially everywhere but Linux. OS X server includes a version of MySQL that doesn't have this issue."
