About two years ago, I made some performance optimizations to the copy 
of pcre
in the httpd-2.0 tree.  I submitted the diffs to the pcre maintainer, 
but I don't know
if they've made it into a subsequent pcre release.  The changes, as I 
recall, were to
remove some mallocs/frees in the regexec function.  They may or may not 
still be
needed with newer versions of pcre, if the pcre code has changed 
since then.
