<P>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.&nbsp; The following pages compare
Boost.regex with various other regular expression libraries for the following
compilers:</P>
<P><A href="vc71-performance.html">Visual Studio.Net 2003 (recursive Boost.regex
implementation)</A>.</P>
<P><A href="gcc-performance.html">Gcc 3.2 (cygwin) (non-recursive Boost.regex
implementation).</A></P>
