Dr. John Maddox (the author of Regex++) did some time trials on the
various regex implementations available
and it appears that claims that "Greta is 7 times faster than Regex++"
are exaggerated
however, in many cases greta does currently beat Boost::regex , however,
the site has a link to an
"experimental recursive version of Boost::regex" which appears to
perform impressively well :)
you can examine the results & the code here :
