[Qgis-developer] Windows refresh rates are slow

[maaza mekuria]

Thanks Ivan. I do not have too many vectors with more points. Most of the polygons are parcel data. I find the QGIS renderer to be slower and was wondering if it is possible to tweak it.

Thank you,

Maaza

Thanks Giovanni for the response. It is entirely vector and I find that the redraws to be very slow. 

I made the suggested changes on using render caching and I do not see that much performance gain.



Is there anything else to do to help the refresh speed?


 By my experience, slow rendering is case when Your layer is containing some very big object (few hundred of vertexes each - for example long contour lines generated by Grass).
