Anandtech tests linux and Mac OS X on the G5
... and finds (again)
that really Mac OS X is
at fault for the very slow (2 to 8 times slower) performance of MySQL on Mac OS X than on linux. Looks really bad for how Mac OS X handles thread and process creation. The "bright" spot: The G5 isn't that bad a processor and can almost compete with the fastest X86 processors.
