The effect seems to occur when a process hasn't been used for a long time and then is suddenly switched from a wait state to an active state. One place I notice it is if I su then perform some function, leave the process su'd say overnight then the next morning type exit on it. The 'exit' takes a while to display then once it does, it takes 3-4 seconds before the previous shell's prompt reappears. The box is never in swap with it's stats being: Mem: 133M Active, 236M Inact, 92M Wired, 15M Cache, 60M Buf, 18M Free Swap: 512M Total, 512M Free However, it has a number of constantly running processes (graphical memory watches, xfishtanks, graphical load watches, etc) Once the process responds it runs fine until the next long delay. It seems more responsive with BETA7 but no where near the same as before the scheduler change. It might be a symptom related to X, will test overnight in console.
