[Qgis-user] QGIS slows PC to a point it is unusable

[Bernhard Ströbl]

Hi Peter,
to me this sounds like a problem with a badly coded plugin. Unload _all_ 
plugins and see if the permformance improves. If it does reload the 
plugins one by one to identify which is causing the trouble.
Of course you can also improve performance by indexing your shape files 
or using another data provider altogeher as has been proposed.

I am using about 6 or 7 ShapeFiles with different filters. I think it is related to the fact that approx. most of them having a rule based styles, some with about 20 rules per layer.
