	<span>Bug <a href="https://github.com/danzel/Leaflet.markercluster/issues/51">#51</a>. Click the button. It will add 1000 markers to the map. this should be fast, but previously in (non-IE browsers) it was very slow.</span><br/>
	<span>Bug <a href="https://github.com/danzel/Leaflet.markercluster/issues/43">#43</a>. Improving performance more.</span><br/>
