Hi Andrzej, I tried different algos, but up to now I did not see any positive effect. I don't have a licence for cGPSmapper. If I got you right, you do this: 1) Create an img file with mkgmap 2) Convert it to *.mp (polish format) with GPSMapEdit 3) Compile that *.mp file with cGPSmapper Finally you compare load those img files to your device and compare redraw times. Please post a link to the two files and let me know what bbox you are testing. Gerd

Hi Gerd,
I have done some tests, compiling maps with cGPSmapper and using different TRESIZE value. Then I have measured redraw time of the map in device.
I think you can observe some effects when decompiling a map with GPSMapEdit. You can find, that long roads are split with additional nodes. I guess nodes are placed at borders of subdivisions.
