Re: [Caml-list] speed

[Chet Murthy <chet@watson.ibm.com>]

[I work for IBM.  Notwithstanding, I'm really not a Java shill.  But,
well, try whatever you do on the IBM JDKs, or the _Sunsoft_ _Solaris_
JDKs.]

Actually, I think you'll find that for tight integer loops and
floating-point stuff, Java is already as fast as good C++.  After all,
that's what the JIT guys optimized first and best.  That said, I've
found that in fact, you can get as good performance from Java, as from
Perl or Caml.  You just gotta really optimize your Java code in
strange (non-JDK-compliant) ways.
