performance: pcre vs perl regex

[gmlvsk2]

Does anybody know difference in performance if
1) I use C with pcre library
2) I use perl

For the same regular expressions looped many times, with remembering
values in parentesis
would 1 be sevaral times faster
or vice verse

Thanks

Only benchmarks on specific machines can answer that. I doubt
anyone is going to run them for you.

Benchmark your code, since that will give you *the* answer for your
environment. Otherwise, provide code we can benchmark on our system (not
promising "we" do though).

3) use TCL


(my) rule of thumb: If it contains alterations,
TCL will win, Perl comes last

Have you tried this with the new trie optimizations in bleadperl? I
would be (very slightly) interested to know if they make a difference.
