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

[Alexandre Neto]

Hi Peter,

Try to use Spatialite, Geopackage or (even better) PostGIS to store your
data and create indexes both on the geometries, but also on the fields used
on the rules you mentioned. That can give you a nice boost.

Hope it helps,
