It sounds like you're seeing pauses related to garbage collection. The
current pre-release version of Racket includes improvements aimed
specifically at this problem.
Can you try a current snapshot to see whether it eliminates pauses?:
http://pre.racket-lang.org/
The program should run better within DrRacket. For best results,
though, you may need to run outside of DrRacket (either by starting the
program with `racket` on the command line or by choosing "Create
Executable" in DrRacket's "Racket" menu).
If the pauses are still not eliminated in the current snapshot, I'm
interested to take a closer look at your program.
Thanks,
Matthew
