[GeoNode-users] Performance issues with tiled layers

Tue Feb 11 06:54:33 PST 2020

Hi Alessio,

I just created 2 maps on the master demo site, 1 with tiled layers and 1 with the single tiles option activated. Both contains the same layers (13 layers).

Tiled: https://master.demo.geonode.org/maps/2309/view
Single tiles: https://master.demo.geonode.org/maps/2312/view

On my computer, the tiled map takes about 35 seconds to load and the single tiles map takes 2 or 3 seconds. It's pretty much the same performances that I have with my installation.

I can try to extrack some network stats from my installation if you need.

Again, thanks a lot for your support!

Maxime

Uhm, currently not.
Do you have any public map that we can use in order to inspect the request?

Or otherwise, can you send some netlog of the time consuming requests?

Hi Alessio,

Thanks for your quick answer. I update django-mapstore-adapter from 1.0.12 to 1.0.17 and django-geonode-mapstore-client from 1.4.6 to 1.4.8 and I dont see a difference, it still takes about 40-45 seconds to load the map. I also tried without any background and there is no difference.

Any other ideas?

Thanks a lot!

Dear Maxime,
it could be probably a performance issue of the MapStore client which has been resolved recently. It appeared with the new versions of Google Chrome especially.

Any chance to upgrade the django-mapstore-adapter and geonode-mapstore-client pip dependencies as follows?

pip install django-mapstore-adapter==1.0.17
pip install django-geonode-mapstore-client==1.4.8

P.S.: remember also that OpenStreeMap lowers down your available bandwidth in case too much requests are issues from the same IP address. Try maybe with different backgrounds.

Regards,
Alessio.

Good day GeoNode users,

I am running GeoNode project 2.10.1 on an Ubuntu 18.04 machine. GeoServer is installed on a different machine on the same server. Everything is working well. However, I am having performance issues with the display of data in MapStore when the layers are tiled. For example, I have a map that contains 15 layers. This map takes about 40 seconds to load when the layers are tiled and takes less than 5 seconds to load when the single tile option is activated. Cache creation is enabled and seems to work (tiles are saved in my gwc directory).

I always thought that using tiles would improve the speed of layer display but this is not the case on my installation.

Do you have any recommendations to improve the performance of my GeoServer installation?

Thanks a lot!

Maxime
