I've been running ULE for a while now and have noticed that I don't have to be in X to see the scheduling problem, I don't even have to be in multi-user mode to notice. Typing and executing commands in single user mode I can see the scheduling is not fluid. For instance, I can type in and execute the sync command so fast that I'm finished before the characters actually get printed and the prompt returns. I don't think it's ever been more than a one second delay, but sometimes it's been close. > I suspect a problem with IPC.
