Here's something weird that I don't really understand. When I leave my OSX iBook on for an extended period without using it (i.e., overnight), and then sit back down to use it, it is really sluggish for the first five or ten minutes. The machine isn't in sleep mode, so there's nothing to wake up from. There's lots of disk-churn, too. Knowledgeable friends have suggested that the OS is swapping out all the user processes. Anyone know how to force it not to do this? Discuss
