Leaflet bad performance with OverPassLayer Markers #38
Description
Im currently encountering bad performance with my Leaflet Map while using the Overpass Library, especially when moving around on the Map although there are not a lot of Markers (less than 100). This is still a problem with limited Zoom Level to 13.
This is a simple example:

latlng = L.latLng(52.5207,13.4093);
var map = L.map('map',{center: latlng,
zoom: 17,
layers: [tiles],
maxZoom: 18,
preferCanvas: false,
});
var icon = new L.Icon({
iconUrl: 'leaf-green.png', //https://leafletjs.com/examples/custom-icons/leaf-green.png
shadowUrl: 'https://cdnjs.cloudflare.com/ajax/libs/leaflet/0.7.7/images/marker-shadow.png',
iconSize: [25, 41],
iconAnchor: [12, 41],
popupAnchor: [1, -34],
shadowSize: [41, 41]
});
var opl = new L.OverPassLayer({
query: 'node["amenity"="bench"]({{bbox}});out;', //show all Benches on Map
markerIcon: icon,
minZoom: 13,
});
map.addLayer(opl);
</script>

Maybe markercluster can be a solution to this, but how do I add Positions from Overpass to a markercluster Layer?
Are there other solutions to this?
