Andrew Morton and others want to change the default value of HZ to ~250 for kernel 2.6.13, "to save power on laptops". I think this is absolutely insane, I should not even have to explain why. If you feel the same way, *please* complain about it on LKML. The thread is called "-mm -> 2.6.13 merge status". They at least need to merge the high-res timers patch at the same time, so that users will not see a regression in the sleep() resolution from 1ms to 3ms. Lee
