[Qgis-developer] map rendering time much longer on windows than on ubuntu

[Denis Rouzaud]

Hi all,

I noticed that QGIS renders much slower on windows than on ubuntu.

This is the configuration:
Windows 7 64 bits
QGIS master from Osgeo4W
vs
Ubuntu 12.04 64its
QGIS compiled on computer

The windows computer is more recent and powerful than ubuntu's one.
I have mainly PostGIS layers.

Is it a know issue/problem/feature whatever?
Is there something I can do to speed up????

Thanks a lot,

Denis
