<div dir="ltr">Hi Henning,<br><br>in Patagonia the poor performance is caused by the LocationHook<br>which has a lot of work to do. The reason are the extremely complex<br>boundary relations like this one<br>http://www.openstreetmap.org/browse/relation/1981462<br>They also cause a lot of CPU usage in the MultiPolygonRelation class.<br>I've added a note that these administrative boundaries are too complex,<br>but I have no idea if anybody cares about it, and I don't dare to change<br>them.<br><br>For Scandinavia I see different numbers:<br>r3246: 460686ms<br>r3247 + small patch: 410354ms<br>which gives ~-11%<br><br>Maybe your server was busy with something else while compiling Scandinavia<br>with r3245, or the small patch I am working on is better than expected ;-)<br><br>Gerd<br><br><br><br><div>> Date: Thu, 1 May 2014 12:42:06 -0700<br>> From: gpetermann_muenchen@hotmail.com<br>> To: mkgmap-dev@lists.mkgmap.org.uk<br>> Subject: Re: [mkgmap-dev] r3239 in performance2 branch<br>> <br>> Hi Henning,<br>> <br>> thanks for the info.
