I grabbed perlbench from CPAN and did some more benchmarks. These
confirmed what we already suspected, i.e. there are no significant
performance differences in Perl itself between 5.6.1, 5.8.0, and 5.8.1,
but the stock Perl on Red Hat 9 (which is compiled with threads) is
significantly slower than a default compile of any recent Perl on the
same system.
All of the Perls that I compiled were done with default options.
The output of perlbench is attached.
