Description

I used this vector (180k records)

http://gis-lab.info/data/orbview-meta/orbview3-catalog-shp.7z

in my test Windows VM with both qgis 1.7.3 and master.

In 1.7.3 it takes 1:10 minutes, in master it takes 7:20 minutes.

Now it is clocked at 2:20, 5 minutes better but still slower if compared with 1.7.3. I fear that with millions of records the difference will grow up easily.

Hi Jurgen, is this a work in progress?
