Sorry I was way too quick on the previous.
I've always heard that you can get faster random numbers by generating a
lot of interrupts. I usually do something like run
/etc/cron.daily/mlocate to generate a lot of disk activity.
And, as I said earlier, depending on how random you want your numbers to
be, you might consider using /dev/urandom, which is a pseudo-random
number generator and is a lot faster than /dev/random.
