[Qgis-user] Opening attribute table for large datasets

[Patrick Dunford]

Is the attribute table failing to load or simply taking a very long time 
to load?

I use some old shapefiles with around 500,000 rows, they are very slow 
loading, it just takes a time, I think is probably the same for a lot of 
large datasets, but it doesn't have trouble drawing the layers on the canvas
