G'day misterperl,

Use Benchmark to check for "significant slowdown".

More generally, "perlperf - Perl Performance and Optimization Techniques" provides useful information.

Also be aware that Perl is being continually optimised: some code might be slower than other code for a particular Perl version; in a subsequent version there may be no difference.

If you post benchmark code and results, we'll be happy to discuss. You may also receive alternative code that you hadn't considered and may be better for your specific needs.
