Ubuntu 9.04 Beta vs. Fedora 11 Beta Performance
C-Ray is another new ray-tracing test in the Phoronix Test Suite and its goal is to be a very simplistic and lightweight ray-tracing engine. While the performance with Bwfirt was similar between the two distributions, Ubuntu 9.04 Beta did noticeably better than Fedora 11 Beta at C-Ray.
POV-Ray is the third and final ray-tracing test used in this article. Ubuntu was faster at C-Ray, but with the industry-standard POV-Ray test, Fedora 11 Beta did better by a significant margin.
While Fedora 11 Beta uses the newer EXT4 file-system by default and is known to deliver better performance as our EXT4 benchmarks have shown (even when benchmarking an SSD), with the IOzone test, Ubuntu 9.04 with the EXT3 file-system did better than Fedora 11. On this system with a Serial ATA hard drive, the 4GB average write speed was 42.54MB/s with Fedora 11 and 48.26MB/s with Ubuntu 9.04.
