SubjectRe: Why HZ on i386 is 100 ?

Picking a timer tick is a bit like picking the color of a
window. Everybody has an opinion and there is no truly "right" choice.
I guarantee you whatever you pick, someone will come along and say:
why not X instead?

A power-of-2 value obviously makes it easy to divide by HZ.

Robert> More importantly, can we change to 1000?

On ia64, you can make it anything you want. User-level will pick up
the current value from sysconf(_SC_CLK_TCK).
