I guess this wasn't the first run when the inline code got compiled?

Right, compilation time is not included. The time measurements were
taken inside the program before and after the method call.

Anyway, since the runtime is so short, in the case of the java version
you're to some extent measuring the JVM startup time.

As above, the timings are from inside the program: so, they don't
include the startup time, but the program did not allow for JIT warmup
time.

Pass --server for best performance. Additionally pass --fast to turn
on experimental optz.

Ditto. CPU-intensive code will often be as much as 2x faster with --server.

It's unfair, result of this program can be determined at compile time,
the haskell one would be fastest ( if there is one

JVM makes plenty of optimizations before it runs program, while starts
very slow. Scripts are faster if startup time is taken into
consideration.

btw, Ruby doesn't have a "char" type, doing a "char" print is of course
much slower...

One of the machines I tested on only had the client vm, so I didn't
include those numbers from the other machines either. However,
--server and --fast on the other machines didn't make much of an
impact on this short test: varying from a nice speed boost on some
runs to slower on others (the test program did not do any pre-test
warmup).

er.

May simply be too short of a test, or the bottleneck isn't in
execution...but I'm sure with some poking around we could get JRuby to
have the fastest result.
