The report finds that Mac OS X on the PowerPC G5 is a viable workstation platform. However, the article concludes that Mac OS X is lacking as a server platform. Lmbench was used to test MySQL performance and measure the bottlenecks at the Unix operating system and CPU level. "Mac OS X is incredibly slow, between 2 and 5(!) times slower, in creating new threads, as it doesn't use kernel threads, and has to go through extra layers (wrappers). No need to continue our search: the G5 might not be the fastest integer CPU on earth - its database performance is completely crippled by an asthmatic operating system that needs up to 5 times more time to handle and create threads."
