I've published that program at the link below. It contains

two lines in the function gen-random-fast where the Hotspot JVM

tells me that the CPU is spending lots of time in
java.lang.Integer.valueOf
(Clojure 1.2.0). I can't seem to get rid of these calls to
Integer.valueOf
even after trying about half a dozen different variations of type-
hinting.
Can anyone else see a way to change the program to avoid those
calls?

I don't get any reflection warnings with (gen-random-fast) on 1.2.
Do you?
Nope. No reflection warnings. But the profiler does show significant
amounts of CPU time spent in java.lang.Integer.valueOf. Maybe it is
mistaken or misleading output from the profiler, but I'm inclined to
believe it so far.
