title: How to optimize MarkerWithLabel on google maps when having too many markers
body: <p>I have been developing an application on google chrome, and I've been using the  MarkerWithLabel library, which i believe is written by google developers. I am using a little over 100 markers on the map and it seemed to be pretty smooth until i checked in firefox (and lets not even mention IE). It is pretty damn laggy in FF. Any way to optimize it? </p>
