Regular expressions performance: Boost vs. Perl

Question

I\'m looking for a performance comparison between perl and boost regular expression.
I need to design a piece of code which relies very heavily on regular expressions, and c

If you really need fast you can get a REGEX content coprocessor. There are two that I know of. Titanic makes a range of processors. Another is made by Cavium. And finally, LSI bought out a smaller company, and is shipping a line of regular expression matching processors.

Theses systems can execute thousands of regular expressions in parallel, rather than one-at-a-time. The most expensive part of using them is moving memory to them and moving them back, and dealing with block-limits, etc.

But if performance is a concern, you might want to try these out.
