AFIAK most Java implementations have a much better threading
implementation than is found in Perl5. This is becase Java was
designed to be threaded from day-0. In Perl threading is very much an
afterthought.
Up until Perl5.8 Perl's threading was essentially useless and even now
you are usually better using forks than threads on Perl.

A Perl programmer could possibly write a solution using 10 separate
processes that would outperform a Java solution. But no even as a fan
of Perl I wouldn't say this alone was sufficient justification to
learn Perl.
