I don't doubt that Java - especially with JIT - can be faster than Perl for some tasks... but "much faster"...? Do you have a citation? And I seem to recall Perl being faster than Java in many areas, particularly, if there's heavy text processing and performing equivalently if there's lots of I/O. Perhaps that's no longer the case (or maybe bias has warped my memory). -- Charles DeRykus -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
