So I was wondering if you had some specific advantage in mind for this patch? Is there some arch-specific advantage? I can certainly envision disadvantages to lower Hz.
My last number I've here is 1% for kernel compile. We're not talking
fancy desktop stuff here, we're talking about raw computing servers that
runs in userspace 99.9% of the time where the 1% loss is going to be
multiplied dozen or hundred of times. For those HZ=1000 is a pure
For desktops 1% of cpu being lost is not an issue of course.
