One thing to tweak is the number of forks - you want to ensure that you
don't have to swap, so sometimes you want to reduce the number of forks.
It's totally dependent upon your infrastructure, so I can't suggest a
number for you.

If you are doing this with rateup, why not switch to rrdtool and skip
the graph generation piece?

bbmrtg.pl reads the logfiles/rrdfiles every five minutes and reports the
values to Big Brother or Hobbit.
