<DIV>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.</DIV>
<DIV> </DIV>
<DIV>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()</DIV>
