Speeding up the visualization of a shapefile with more than one million of lines {Scanned} {Scanned}

Hi Luca,

You can use scale dependent display of layers, generate a simplified layer 
for smaller scales (for example create a layer from the streets/public 
areas only). The tiled layer should be displayed only at large scales.
The fasters solution is if you pregenerate the overview layer instead of 
on the fly generation with for example FILTER.

Bye
Zoltan
