Hi Gerd Yes - use the patch Still not sure why there is a change in performance here though. Ticker On Tue, 2017-02-14 at 17:44 +0000, Gerd Petermann wrote:

your style is very special because it adds all polygons with resolution 10.

Hi Gerd,

i build 12 tiles. 3804 needs 11 minutes for that, 3796 only 5 minutes.

The style is not the default. Its the style from my "speichenkarte.de"

Hi Arndt,

if you use the default style please try r3804.

Hello @all,

mkgmap-3803 needs for 1 map-tile 2-3 minutes. mkgmap-3796 (or older) needs only 15-30 seconds.

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?

(Buy a faster PC :))

greets

Arndt

OK, r3808 solves the performance problem in ShapeMergeFilter. ________________________________________ Von: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> im Auftrag von Gerd Petermann <GPetermann_muenchen@hotmail.com> Gesendet: Mittwoch, 15. Februar 2017 09:47:59 An: Development list for mkgmap Betreff: Re: [mkgmap-dev] Performace mkgmap-3803 Hi Ticker, the performance problem with that special style is in ShapeMergeFilter. I think the reason is that the new code in MapSplitter etc. puts a lot more shapes into one sub div, esp. at low resolutions, and ShapeMergeFilter doesn't work well in that case as it starts to do lots of seq. seaches. I'll try to find a better solution for that.

Hi Arndt, good to know. The patch filter-early-v1.patch will probably further improve run time for you. I'll try this tomorrow.
