This is running Eclipse with our interpreter (although the core java
libraries are native code). Very little work has gone into optimizing
the interpreter. Virtually all VMs these days JIT compile the bytecode
to native code at runtime before execution. That's where all of the
optimization happens as well, since javac developers gave up optimizing
bytecode a long time ago. So I was surprised with the performance
considering we're running unoptimized bytecode on an unoptimized
interpreter.
I think a good next step is to start compiling some of Eclipse's jar
files to native shared libraries. I think, however, that we'll need one
more patch (from Jeff, hopefully!) before that will be possible.
