The Jikes compiler (as far as I know) is basically javac written in C
instead of Java, so it compiles much faster. Run time performance is about
the same, I think. I download David's Euphoria/Java and made some small
tweaks so it's a bit faster, though it still doesn't do enough
optimization to approach Euphoria's speed. However, a hand written Java
program can easily beat an equivilent Euphoria program. Here's the results
of the sieve benchmark (though i only ran each once, so they're not
perfect):
Euphoria/Java with my tweaks, compiled by javac -O: 373 sieves/second
Euphoria/Java with my tweaks, compiled by jikes -O: 396 sieves/second
C++ with gcc (no optimization options): 16023 sieves/second
gcc with -O3 -fomit-frame-pointer: 46560 sieves/second
gcc with -O3 -fomit-frame-pointer -march=pentiumpro: 51600 sieves/second
hand written java w/ javac -O: 40051 sieves/second
hand written java w/ jikes -O: 34633 sieves/second
Euphoria for linux: 7536 sieves/second
