IMHO benchmarking can be very tricky to do well and acurately, especially with perl and how very flexible it is. I have looked at a lot of benchmarks on the net and this site, some good, some bad, but I have yet to find a good set of over-all benchmarks that show the progressions of Perl through it's version changes.
Does anyone know of or have a good link to such a resource? Or better yet, what are the best resources that you know of when it comes to benchmarks, Perl vs. Perl or Perl vs Other...
