Hi Andrzej, thanks for testing. I also think that the possible improvements are rather small. I'll try a few more changes, e.g. splitting large objects earlier, but I don't expect any big improvements. A typical case where it would help is a long diagonal line. The bbox for it is very big, and a split in the middle would produce two much smaller bboxes. Splitting an rectangle like that for the background earlier will probably not help at all.

Hi Gerd,
patch v3 is working. I have done some speed test on nuvi but conclusions aren't clear. My feeling is that your original settings is a bit slower than standard mkgmap. I have tried some values and settled to:
LARGE_OBJECT_DIM = 8192; int wantedSize = MAX_RGN_SIZE / 4;
This seems to be a bit faster than standard mkgmap, maybe about 10%, sometimes more. But redraw times aren't always repeatable and my tests are limited to single nuvi model. I would rather say, that there is no significant improvements.
