70+ layers seems a lot to load. Do you need all of them at the same time? I would suggest grouping them. For instance in one of my applications I load land parcels + roads + address points as a single layer - in my case they are never edited, so I request them as a single WMS call to Mapserver. You might be able to set up some buttons on your page, that load / unload groups of layers using OL's javascript functions such as map.addLayer() and layerRef.destroy() Regards, Robert

It takes roughly 9 seconds to load the 70+ layers. Is this normal? Is there a better way to do this as I am at a loss. In chrome everything seems to load quickly, but in firefox there is a considerable lag time, it also seems to force the browser not to respond for 3 or 4 seconds. of course IE is just terrible and never worked well there. I am also adding a large number of features across these layers, it seems the more and more i look at it the answer seems to be a feature sever, is this wise? will this load 1500 points into these 70+ layers more easily?
