Ubuntu 10.04 Alpha 2 vs. Early Fedora 13 Benchmarks
Given that early benchmarks of the Lucid Lynx were less than encouraging, Phoronix decided to take the latest alpha out for a spin and has set it side-by-side with an early look at Fedora 13. "Overall, there are both positive and negative performance changes for Ubuntu 10.04 LTS Alpha 2 in relation to Ubuntu 9.10. Most of the negative regressions are attributed to the EXT4 file-system losing some of its performance charm. With using a pre-alpha snapshot of Fedora 13 and the benchmark results just being provided for reference purposes, we will hold off on looking into greater detail at this next Red Hat Linux update until it matures."
What often really matters are the upstream apps. Often, other than reporting an upstream bug in an application to the developer, there is not much one can really do about bugs in upstream applications like KDE. I am seeing that now with KDE and X.org. Currently, there is a bug in evdev and dga in X that prevents X from working right with a Wiimote. It can't really be fixed by the distributor. Only X.org can fix it.
So far I have:
Broken Sound effects on Stratagus. (Mandriva 2010.0)
Broken GLX Support on QuakeForge. (Mandriva 2010.0) But DarkPlaces Quake still works.
Broken Wiimote Support in the evdev driver.
These are just a few examples of applications that don't work becaues of a problem upstream.
