They're directly proportional to clock speed on modern x86 CPUs.  (Looks
like 2x MHz from the values Jim quoted.)  It has little correlation to
machine performance but is used internally by the kernel for timing
things.

That's not true.  Early Celerons are based on a Pentium III but the
later ones are Pentium IVs with cache ripped out.

Other than that, yeah: Celerons suck and C compilers _really_ love cache :-)
