Fedora 13 vs. Ubuntu 10.04 LTS Benchmarks
Again, there is no definitive conclusion to draw from the NAS Parallel Benchmarks results.
With the new TTSIOD 3D Renderer test profile there is some slight variation in the results between the newest releases of Ubuntu and Fedora Linux. Ubuntu 10.04 LTS was slightly faster with this test profile when running on the quad-core Opteron setup, Fedora 13 came out ahead on the Core i7 notebook, and with the Intel Core i3 desktop the winner was Ubuntu 10.04 LTS.
For most of the tests that are just heavily dependent upon the CPU, the stock performance between Fedora 13 and Ubuntu 10.04 LTS is nearly the same even though there are slight differences in their compiler, Linux kernel, and other components. Concerning the graphics performance, Fedora is the winner, but that is no surprise at all. Fedora 13 ships with a newer release of Mesa and has newer DRM code and patches than what is available in Ubuntu 10.04 LTS. Red Hat always ships the most updated open-source Linux graphics code in Fedora, which usually gives it a leg-up in terms of features and performance. However, this is for the open-source graphics driver. In regards to the disk performance, both Linux distributions currently use the EXT4 file-system by default and their performance is close aside from a few EXT4 changes found in the newer 2.6.33 kernel.
