[mkgmap-dev] Optimizing MapSplitter

Thu Nov 13 12:20:42 GMT 2014

Hi Gerd,

I test maps at my current location, which is near the center of Gdańsk, 
so it is rather dense map here. This 50% difference was in redraw time 
from nuvi menu "Dispaly Map" to fully rendered map. It was about 4 
seconds for mkgmap and faster cgpsmapper and about 6 seconds for slower 
version of cgpsmapper compilation.

Some more statistics:
