Is boost::regex_merge able to parse more than 20kb 
data per sec?

 I'm using a function like the following, and cant get it 
above that rate..

std::string RegExpBinReplace(LPCSTR szWhat, 
std::string szWhere, DWORD len, LPCSTR 
szReplacement)
{
	const boost::regex e
(szWhat,boost::regbase::normal);
	std::ostringstream t(std::ios::out | 
std::ios::binary);
	std::ostream_iterator<char, char> oi(t);
	boost::regex_merge(oi,  szWhere.begin(), 
(szWhere.begin() + len), e, szReplacement);
	return t.str();
}
