I wasn't aware that such performance issues were divorced. In my admitted limited view, a laggy mouse is a laggy mouse, and its due to irq latency in achieving the context switch to service the mouses data. To me, its sorta like 2=2. :)

Ok Nick. I'll reboot tomorrow without the elevator argument. Right now, amanda is fixin to be fired off in about 25 minutes and I want to see how badly its estimate phase hogs the machine using the cfq scheduler. With the -mm2 as, it was almost psychedelic to watch the mouse move.
Also off topic re mouse performance, and I expect this is an X issue, but when its been blanked because I'm typing, it takes about a full seconds worth of hand waving before it becomes visible again. This is an X issue and I should go away, right?

So beit. I guess I must be one of those. (-:
