I didn't and still don't, but didn't know that at the time I configured my
system that way. I was following some of the (x86-centric) instructions
for polling my fxp NICs and noticed a tremendous performance degradation,
and that's when I learned that setting HZ=1000 on my particular Alpha is a
Bad Thing.
