Map is very slow to render polygons

Riccardo — Mon, 20 Dec 2021 21:38:40 GMT

Hello,

Qlik Sense Map is very slow to render many polygons.

I have like 10.000 polygons to render above a nation. Map is slow to do it, but the server has both the CPU and ram low consumption %.

I have GeoAnalytics Plus and I'm using Qlik Sense Native Map, but Qlik Sense GeoAnalytics Maps has the same problem.

I have these polygons on QVD, therefore on a Resident.

Are there other way to load them faster?
Since I only have to analyze Italy, can I create a customized map with the map and my polygons as if they were integrated into the map?

Thanks

Riccardo

Hi Riccardo, maybe polygons have many dots? if so try with "Simplify" to reduce number of points to draw

I tried to do an AutoLow. But map persist in slow loading..

Hi, have you checked if the points for each poligon are really less than before the simplify?

I have no more ideas on why is running slow.
