yup. In JVM implementations, the link to the meta level is not as
direct as in Smalltalk VMs. This explains why Squeak is better off
than Java.

VW still being *much* better is interesting, though. Perhaps the JIT
compiler kicks in, or the interpreter is much smarter. In Squeak, it
can't, and in Java, it doesn't. (At least here: Macbook Pro running OS
X, Apple JVM 1.5.0_07, verified by running the "benchmark" both with
"java" and "java -Xint".)

Could someone with access to VW VM internals please tell me what
happens in there? I'm curious. :-)

Best,

Michael
