[section:performance Performance] The performance of Boost.Regex in both recursive and non-recursive modes should be broadly comparable to other regular expression libraries: recursive mode is slightly faster (especially where memory allocation requires thread synchronisation), but not by much. The following pages compare Boost.Regex with various other regular expression libraries for the following compilers: * [@../vc71-performance.html Visual Studio.Net 2003 (recursive Boost.Regex implementation)]. * [@../gcc-performance.html Gcc 3.2 (cygwin) (non-recursive Boost.Regex implementation)].
