I have two identical machine, with the exact same hardware. One is running a fully updated version of Fedora 8 Test installed a few months ago, the other is running the official Fedora 8 Release, also fully updated, installed about 1 week ago.
What confuses me, is that the "Release" version of Fedora 8 is, without any doubt, MUCH faster than the machine running the "Test" release. Initially, I just assumed the machine running the "Test" release was slow due to less-than-ideal hardware specs (512 Megs RAM, 1.2GHz processor). However, after installing the "Release" version on another machine with the same hardware, I realized the hardware specs were more than adequate (the "Release" version is blazingly fast).
Does the "Test" version have a lot of debugging code enabled with more verbose logging? Enough to make it slow to crawl? Whereas, the "Release" version has all the debugging code switched off? I've checked the logs, they look about the same, but that doesn't mean the "Test" release isn't running with debug flags compiled in. It's such an obvious difference, that I'm tempted to install the release version on the other machine (but would rather not).
