[GeoNode-users] Poor performance GeoNode

Can you please better explain what you mean with "Map Performance" exactly?

Getting the list of layers or rendering the map?

Also, how many layers you have and which type (vectorial / raster) ?

Are you able to identify performance issues? Those are on GeoNode or
GeoServer?

In the first case it is certainly an issue of your HTTP Server
configuration (and most probably the proxy module), in the second case it
could be an issue of data not correctly processed.
