Stumpled upon this story the other day. Finally a tool where you can actually decide which things get prioritized instead of the kernel relying on heuristiscs. I did a test with alsaplayer playing back using through jackd (very sensitive to not getting enough time slices). To stress the system I did a emerge sync together with a fetchmail process sucking down the days mail. I don’t really care if it takes 5 seconds longer to fetch my mail or if it takes 2 minutes long to emerge sync as long as I can be sure that my music doesn’t skip. And guess what? With DeskOpt you can 🙂
