Hi Ticker, some more details: I didn't think of boundary relations like r1959008 which contains > 700 outer rings. For each node close to that boundary mkgmap called Java2DConverter.areaToSingularAreas() which calculated all the areas again and again. In Germany, boundary relations typically have only one ring ;) I think I should look into the code which compiles bounds.zip, somehow I expected that those complex areas are split to singular areas, might improve performance.

Fixed with r4469. I'll probably also remove the methods pointInsideArea() and pointInsideSingularArea() in BoundaryUtil.

Hi Ticker,
will look at it tomorrow. Maybe you can upload the file to http://files.mkgmap.org.uk/

Hi Ticker,
please tell me the tile boundaries

Hi Gerd
With the current version I have a tile that takes 3.5 hours to build. With an old version (r4295) it took about 3 minutes. Without - -bounds it takes 1 minute 15 secs.
Relevant options are: --bounds=bounds.zip --location-autofill=is_in,nearest

The old version had similar lines, but the stats at the end are:
