No. We did a very basic query system on one of the overall tile servers at the beginning. Sven improved that a lot by restricting the number of concurrent requests for tiles and load balancing among servers (a, b, c). Given how the system is written, I suspect that if one of the tile servers is faster, it will get more requests.

More, RTOSM now will do a file-based cache of the tiles, so, if you prepare the demo beforehand, then your Pharo will have preloaded the tiles and will not tap into the tile servers.

We still have unexpected latency issues, but I haven't added a time trace analysis to the Jejak tracer. It's on my todo list.
