[mapguide-users] How long will it take to generate tiles by MgCooker

[Stefan Dalakov]

I was fighting with this few days ago. It seems, that tiles are 
generated not for the extents of the base layer being tiled, but for the 
extents of the largest layer from the map. What I had was county map, 
not very detailed, with one municipality with full detail. I wanted to 
create tiles for this very detailed part (approx. 1/20 in both 
dimensions). And the surprising part was that "empty" tiles, which are 
400 times more than the "useful" ones, were not generated faster. I 
guess Daniel is facing the same problem.
