Ubuntu 10.04 Alpha 2 Benchmarks With Early Fedora 13 Numbers
The IOzone 8GB write performance was the same between Ubuntu 9.10 and Ubuntu 10.04 Alpha 2, but Fedora 13 (2010-01-13) was noticeably lower: 66 vs. 52 MB/s.
Ubuntu 10.04 Alpha 2 regressed when it came to the 8GB read performance in IOzone, but Fedora 13 was reading at even a slower rate.
The PostMark disk performance between Ubuntu 9.10 and 10.04 Alpha 2 was close while Fedora 13 was behind, but again given the debugging options used during the development cycle and its pre-alpha state we aren't worrying too much.
