I am looking for the most efficient open-source C++ regex library.

Reading this article: http://swtch.com/~rsc/regexp/regexp1.html - It
seems that GNU awk is the best overall:

This is all true, but also completely irrelevant. DFA's have good worst case behaviour, but can be many times slower for common cases.

I'd be very interested in seeing the data that show this.
