I have switched to a new map renderer for the 2D maps and removed the flat maps from the 3D maps software. The 3D maps software updates the map on each edit and therefore creates a lot of processor load. The lot map is only created every day once with another rendering software. I hope that we will have less risk of lag. Currently the server mostly complains about chunk loading and map rendering as processor load causing items. There is some strange pattern/noise now on the 2D map that I am trying to fix however.
