You are probably using the IA32-native version of Larceny,
which automatically compiles everything you run, load, or
type.  Pre-compiling eliminates the compile time, but the
run time will be exactly the same.

If the code is too slow, it's probably because Larceny's
implementation of SRFI 19's random-integer is slow.  If
you don't need high-quality random numbers, then you
could use a faster implementation of random-integer.
Larceny's implementation of random-real is probably fast
enough, especially if you're using the current development
system.  (I improved Larceny's implementation of SRFI 19
just a few days ago.)
