[Jscheme-user] 20% improvement

[Ken A. <kan...@bb...>]

After talking to Joe Marshal, and getting JScheme working in 1.5.0, i thought i'd write a cartoon document describing how JScheme works.  I also hoped it would lead to identify opportunites for optimization.

One thing i found was that Scheme.execute() which calls Scheme.currentEvaluator().execute() was happening a lot.  So i added an Evaluator argument to most of those sites.

This lead to a 20% improvement in the Gabriel benchmarks.  Not a bad thing to do during OOPSLA (though i didn't go).
