Red Hat Perl performance problems

As demonstrated by this blogger, there are known performance bugs when using the Red Hat builds of Perl and the bless/overload combo.

Apparently there's a patch in the pipeline that has yet to get into the Red Hat packages yet, and you can compile Perl yourself and bypass the problem all together.
