I suspect you might have a slightly biased view on this. ;-) Yes,
HZ=1000 makes some problems easier to convert ticks to real time, but
slower to convert real time to ticks.

Besides, the Linux kernel MUST work with (fairly) arbitrary HZ values,
because some platforms just don't have much of a choice (e.g., Alpha
is pretty much forced to 1024Hz).

But, yes, on ia64 we can choose HZ to our liking.  If someone presents
evidence that shows a real benefit for a value other than 1024, I'm
certainly willing to listen.
