[Boost-users] http://www.boost.org/doc/libs/1_39_0/libs/regex/doc/vc71-performance.html

I have a couple questions. http://www.boost.org/doc/libs/1_39_0/libs/regex/doc/vc71-performance.htm l references PCRE 3.9 but http://www.pcre.org/ says that the current version is PCRE 7.9. I would really like to see current values for performance comparisons. Where would I get the software for this comparison? Is the source part of the Boost library? Thanks, Jerry
