Perl's development speed is faster, but from what I've seen of Java, trying to code 00 Perl in the style most Perl programmers use seems to be quite a bit slower. Compare the speed of Lucene versus Plucene or XProlog versus AI::Prolog. Perl loses hands down. These started as straightforward ports which is part of the problem, but their coding styles don't seem significantly different from what I see many Perl programmers use.
On the other hand, I hear people claim that when Perl is coded in a more idiomatic style, it competes quite handily, but I'd like to see benchmarks against real-world applications rather than samples.
