The most obvious solution, to me, would be to compile to byte code.
Check the docs, mzc is able to do this, I don't rember if anything
directly in drscheme lets you access this functionality, but if not,
just go to the command line and use the appropriate mzc function.

For instance, you can use the -z option.
