I wouldn't know about that. The program doesn't do anything but write to the
display. I can't believe that a secure interpreter could be 3x slower.

I just believe that the JIT compiler in OS/2 is doing a very poor job.

Secure or not, I can't believe Java will "save" OS/2 if it's 3x slower than
on Windows NT 3.51, which has a reputation as a hog.

Meanwhile I'm sitting here with IBM's free but "broken" Java port, and *3*
different Java ports for NT (Sun's, Borland's JIT compiler, and Microsoft's
(boo! hiss!)), two of which are also free, as far as I can tell. I can't see
where OS/2 has any sort of advantage here at all.

My system is only as secure as the lock on the door. And I'm nervous about
browser "cookies". But that's another story altogether.
