No problem, I supposed that it was an error in translation!

Hecl is certainly much slower than Java! It is interpreted, vs
compiled to byte codes that may even be JIT'ed (just in time compiled)
on some platforms.  You don't want to use Hecl for anything
performance intensive.  What you could do, though, is create a Hecl
command in Java that does performance intensive work:

class CountCmd implements Command {
    public Thing cmdCode(Interp interp, Thing[] argv) throws HeclException {
        int n = IntThing.get(argv[1]);
        int i = 0;
        while (i < n) { i ++; }
	return argv[1];
    }
}

In other words: don't try and write a fast action game in Hecl - write
it in Java, and use Hecl to add make it possible to configure the
game, or add new levels or otherwise extend it.

Lists and hashes are pretty important, especially the former, if you
ever want to deal with more than one thing.  ListThings are also
fairly integral to Hecl's functioning.

For instance, an error / stack trace is a list of procs (and can be
manipulated with the list commands).

Uncompressed, for normal Java, Hecllib.jar is only 80K, and that
includes some networking code (http).  You could probably work on the
files in core/ to eliminate what you don't need, but I think you'll
find that it's already a fairly minimalistic system.
