Yep, I wrote GRETA. GRETA /was/ faster than Boost.Regex pre-1.31. Since then, Boost.Regex has been rewritten to be much more efficient. Boost.Regex and GRETA are now pretty close in performance.
I wrote GRETA while at Microsoft, and the code is owned by them. I started writing xpressive when I left Microsoft. It is a ground-up reimplementation, not a rename of GRETA. GRETA is no longer being actively maintained.
xpressive takes the virt-call-elimination trick to the extreme, using expression templates to eliminate *all* virtuals.
