See the attached code, I'm needing this to be as fast as possible - if you can see any improvements I could make I'd be very grateful.

unsigned int countNeedles(vector<unsigned char> &aHaystack, vector<unsigned char> &aNeedle){
	vector<unsigned char>::iterator resultPointer=aHaystack.begin();
	unsigned int occurences=0;
		resultPointer=search(resultPointer, aHaystack.end(), aNeedle.begin(), aNeedle.end());
	return occurences;
