+
+== Overview ==
+
+Add support internally to the MapGuide Server Engine to render larger tiles
+and then slice them up into the normal tile sizes
+
+== Motivation ==
+
+It's much efficent to render one large tile than many small ones. 
+
+== Proposed Solution ==
+
+Add a meta tile factor to the tile service, which then will render larger tiles
+and then slice them up into the smaller tiles which get served to clients.
+
+== Implications ==
+
+The current approach with polling for lock files is inefficent and 
+is excaerbated by meta tiling. When using a meta tiling factor of 4,
+15 tiles will wait and poll for 1s while the meta tile is rendered
+and sliced up.
+
+Changing to a mutex would help
