Hi Arndt, your style is very special because it adds all polygons with resolution 10. I assume that this is the reason for this because other style did not show a change in performance. @Ticker: Maybe we can use the patch from this thread ? http://gis.19327.n8.nabble.com/Minimum-resolution-in-polygons-style-tc588789...

My PC is an older model. IntelCore2 Duo 3GHz 6GB RAM 64bit win10 mkgmap starts with this: "java" -jar -Xmx3300M -enableassertions -jar ..\..\mkgmap\mkgmap\mkgmap.jar Can i anything do?
