the sad part is that the HRT patch completely removes *any* dependency on the timeslice or timer interrupt frequency. you get timing by reprogramming the APIC so that it interrupts the CPU at exactly the right time. the APIC has usec resolution for this. its a much better design than just cranking up HZ, and in fact, I would probably leave HZ at 100 with this patch in place. >Open source is a bit slower to move, but at least it sticks around! So true. Anyway, at least there will be a patch; the most recent one for 2.4.20 just came out. --p
