| Sep 1, 2012 at 3:41 | comment | added | user9907 | Assuming there are always going to be factors that make the rendering slower or faster, I think the best scenario is to move to a background rendering thread that doesn't lock up the whole application while it's working. I love QGIS. It is very stable, but it can take several minutes to re-render the view and it just blanks out the whole lot and redraws it completely. All my layers are file-based and can be up to 1 GB per map (the majority of this is large GeoTiff relief backgrounds). This is probably always going to be slow, but QGIS could put the rendering into a separate thread, and make it | |

| May 2, 2012 at 0:00 | comment | added | djq | I noticed that QGIS 1.7.4 connecting locally to my PostGIS 2.0 database is extremely slow on my powerful windows computer, but it works speedily on my much slower Mac(OSX). I haven't figure out what the problem is either..... | |

| May 1, 2012 at 14:38 | comment | added | nhopton | Could this be the labelling issue? It might be worth rendering the layer without labels to see if this makes a difference. | |
| May 1, 2012 at 14:30 | comment | added | MappaGnosis | Do you get the same problem with other data layers or is it just this one in particular? If so, I wonder if there is some invalid geometry in your data, or even a large amount of null geometry. | |

| May 1, 2012 at 13:56 | comment | added | Simbamangu | This does sound unusual - QGIS usually performs very well compared to other GIS systems. I'd suspect some sort of delay with the remote database, though it sounds like a small set of data. What other data do you have loaded? | |
