I've been trying to repeat a case of priority inversion I experienced with O18.1...but it seems to be cured (and that was really my only problem with it). I was already getting fewer skips in XMMS with 2.6.0-test3-mm2 than I did with 2.4.18 and the same sort of workload. I can't really test xmms now that the ACPI changes have obliterated my chances of freeing IRQ 5 for my sb16 -- but from the improvements I feel in the last few patches from Con, I imagine that it wouldn't skip anymore. (On a side note, I really miss xmms where random means quite random, unlike my CD changer which is repeat the same songs in a four hour block.) I certainly am not running any sort of high-end machine with a K6-2 400 ;-) The mouse might lag slightly for a few seconds when starting up a build, but as soon as the scheduler adjusts, I can't tell whether I have four builds running at the same time or just one. In 2.4.18, it has a slow feeling that let's you know the system is loaded -- and it never goes away (well, until the compiling's done). -Wes-
