Thanks for your reply David,
Unfortunately my original problem was that System.Random.{random,
randomR} is used instead of all these weird test functions that I came
up with during experimentation. And I can't force anything inside StdGen
so I see no way of speeding up the original program sans replacing the
random number generator itself. When I did that I became about 4 times
faster than with System.Random but still an order of magnitude slower
than for instance by using the Java implementation (and I can confirm
that (^) is *very* expensive in this context).
Many thanks again,
Thoralf
