After 100 turns:
2: update_map_canvas_visible: 43,916252s from 490 calls
2: unqueue: 36,182100s from 390 calls
2: update_map_canvas: 51,305540s from 7420 calls

CMA local CPU time is 3.3s:
2: CMA: overall=3,364782s queries=4007 0,839726ms / query
2: CMA: apply_result: ignored=92.2% (3696) applied= 7.8% (311) total=4007

Waiting for the server (network):
2: A:SMA: waited 4,085804s in total for network; requests=83; waited 83 times
2: A:CMA: waited 44,630560s in total for network; requests=644; waited 318 times
2: A:GA: waited 24,971887s in total for network; requests=742; waited 742 times

So the drawing costs us about the same time as waiting for the server
(2 * ~1min) while the actual CMA calculations only took 3.3s.
