[OpenLayers-Users] More than 20 wms layers, performance issues, geowebcache concurrency

You bust build serverside a "proxy" code that, for each layer in your
single WMS request that is made clientside, calls single geowebcache
layers, grab the tile, and then merge the tiles in a single tile that
send to the client.
