Last year we provided benchmarks looking at Ubuntu versus Mac OS X when it came to using the latest releases for both softwareplatforms at the time. Both operating systems had performed competitively -- in some tests, the Apple OS wound up on top while in other areas Canonical had the advantage. Since that article back in November, Apple has released a minor update to Leopard (v10.5.6) and Canonical last month released Ubuntu 9.04. We have already looked at the performance of Ubuntu's Jaunty Jackalope, and even found it to perform with old hardware, but how does it now compete with Mac OS X? We have more benchmarks this morning to continue this performance investigation.
