Just pushed a significant performance improvement to SVN. Saves about 15 seconds on what was a 69 turn second in my current game. The saving increases proportionally to the total number of buildings in the world, so laregr maps and later games will see the most improvement (my 15 out of 69 seconds was a gigantic map in mid-medieval period)
Is this on top of the performance boost Karadoc pushed a day or two ago?
