android map is moving slow after many overlays added

My app has alot of overlays on the map, how do i keep the map from being so slow? Its like a 5 second delay when moving around on the map. Take a look at my code below on how i am adding people and can someone show me how to fix this so that its not so slow, I have about 80 overlays on my map and growing by the second.

ArrayList<String> lstotherslocation = MyGlobalInfomation.getOthersLocation();
              List<Overlay> mapOverlays = gMapView.getOverlays();
                Drawable drawable = this.getResources().getDrawable(R.drawable.otherslocation);
                OthersLocationOverlay otherslocation = new OthersLocationOverlay(drawable,this);
                mapOverlays.clear();
                for(int i = 0; i < lstotherslocation.size();i++){
                    number = number + 1;
                      OthersPoint = new GeoPoint((int) (Double.parseDouble(lstotherslocation.get(i).trim())),
                                                (int) (Double.parseDouble(lstotherslocation.get(i + 1).trim())));
                      OverlayItem overlayitem = new OverlayItem(OthersPoint, "Title",
                      "test: " +  lstotherslocation.get(i+ 2) + "\n" +
                      "User: " + lstotherslocation.get(i+ 3) + "\n" +
                      "test: " + lstotherslocation.get(i+ 4) + "\n" +
                      "test: " +  lstotherslocation.get(i+ 5 ));
                    i = i + 5;
                    otherslocation.addOverlay(overlayitem);
                    mapOverlays.add(otherslocation);

Is there a reason why mapOverlays.add(otherslocation) is inside the for loop ?

Can you try with the following code :

OthersLocationOverlay otherslocation = new OthersLocationOverlay(drawable,this);
mapOverlays.clear();
mapOverlays.add(otherslocation);
for(int i = 0; i < lstotherslocation.size();i++){
    ....
    otherslocation.addOverlay(overlayitem);
}

I assume you want to have your 80 markers on the othersLocationOverlay ?
