+--- | > class files slightly differ in size.

The source code to Jikes can of course be perused now. :-) As for real-world speed... doing a clean build of one of our projects (about 850 .java files to compile): with javac (no JIT): 1401.93 real 1261.02 user 32.17 sys with jikes: 112.32 real 45.05 user 14.61 sys I love jikes. +--- | So far I've been using jikes to develop 'production' code, and given | that there aren't any significant optimizations in either javac or | jikes, I feel pretty safe with it now. +--- The only thing to be careful of is if your code needs to be deployed on a Java 1.2 (the "Java 2 Platform") system. Last time I tried it, the Jikes compiled code didn't pass the 1.2 verifier. Gene -- Gene W.
