[Qgis-user] QGIS layer control very slow

[Mike Flannigan]

Yeah, that is a raw deal.  On Win7 64b QGIS 2.4.0 I can
turn on a layer of roads for a whole state (650,000 line
features) in 4 seconds, and turn it off instantly.  When
I include the road name labels it takes about 32 seconds
to turn on (render) and it turns off instantly.

My computer is fairly fast for an old computer.  AMD 6200 Six
Core processor; 3.8 GHz; 8.0 GB ram.
