If you're referring to the one I have indeed read, then that's just one
comparison which is against Sun's Solaris JVM and is non-representative
of other JVMs, and is based largely on API/Framework issues which would
largely be replaced by GTK+, gnome-vfs, etc.

Yes, I should have noted I meant with JIT or AOT compilation.  That
doesn't mean, of course, that the GNU Classpath libraries (or official
Sun libraries) are well optimized.  They probably aren't.  I know a
number of official Sun packages are actually rather horrible performance
wise; that's a problem in the library, tho, not the core language.

Also, for the record, don't assume that Java's runtime speed has
*anything* to do with Mono/.NET runtime speed.  They really are quite
different in many respects, and .NET had a lot more thought put into it
to get quite high speeds.  Miguel has explained these elsewhere in one
of the bazillion threads on this subject...
