Last week we published Ubuntu 9.04 vs. Mac OS X 10.5.6 benchmarks where we compared the performance of these two popular operating systems on a Mac Mini. With the OS X kernel currently being 32-bit but with support for 64-bit applications, we had used the 32-bit version of Ubuntu 9.04.

In a majority of the Leopard operating system from Apple outperformed Canonical's Jaunty Jackalope, but today we are adding in the results from an Ubuntu 64-bit installation. As you can see from the results, the x86_64 version of Ubuntu Linux is more competitive against Mac OS X 10.5.6. 

We used the same hardware and software configuration as our earlier article when running this 64-bit Linux test. The Apple Mac Mini was loaded with an Intel Core 2 Duo T5600 clocked at 1.83GHz, an Intel 945 + ICH-7M motherboard with integrated graphics, 1GB of DDR2 memory, and an 80GB Hitachi HTS542580K9SA00 HDD. The kernel reported on OS X 10.5.6 is 9.6.0 i386, X Server 1.3.0-apple22, OpenGL 1.2 APPLE-1.5.36, GCC 4.2.1, and a Journaled HFS+ file-system was used. Ubuntu 9.04 uses the Linux 2.6.28 kernel, X Server 1.6.0, xf86-video-intel 2.6.3, OpenGL 1.4 Mesa 7.4, GCC 4.3.3, and an EXT3 file-system...
