My test data is 10776 Polygons.
PostGIS provider: use spatital index for geometries
- Faster when zoom in ( a little geometries in bbox) : Edit fast ( realtime :ok)
- Slower when zoom out. When zoom to extent take about >1 minute (
this is a limitation
in my application)
- I seem to
meet almost not much different time
in different zoom levels. Slower than postgis when zoom in ( a little geometries in bbox ) and faster
than postgis when zoom to extent.
When zoom to extent take about 10 seconds
I will try to add Quadtree to GeometryFeatureProvider.
I do not have much experience with it
