[Qgis-user] Show background processes

[Jonathan Moules]

Hi Clay,
Can you not simply turn off all layers and then enable them one at a time until things start going slowly again? That should quickly highlight the problem layer.

Also, do the layers all have spatial indexes?
Cheers,
Jonathan

Is there a way to show the background processes that are causing QGIS to take 10 to 20 minutes to refresh a map view?

I recently moved some layers to a local network drive that is very fast otherwise and the file has become unusable.  I get "(Not Responding)", Windows circle of death and the back and forth status indicator on the QGIS Status Bar for a very long time.

I can't pan, select, zoom or do really anything without causing a 10 or 20 minute delay while QGIS refreshes the view.

This project had many other layers that were on this same drive before the issue started.  So I am fairly confident it is not the drive.

Is there a list of GIS file types that do not perform well on networked drives?

The file types this project has:

  1.  geojson (some layers previously on the same network drive with no previous issue.)
  2.  shape (about half of the layers previously on the same network drive with no previous issue.)
  3.  sqlite (about half of the layers previously on the same network drive with no previous issue.)
  4.  gpkg (some layers previously on the same network drive with no previous issue.)
  5.  various raster layers (most previously on the same network drive with no previous issue.)

I would really prefer not to have to delete everything and start form scratch building the project up one layer at a time in order to identify which layers are causing the hang.

thanks

Clay
