Hi Radim
Wow, there are a lot of performance critical changes, even with the
postgresql layers. Thank you very much for the useful qgis_bench, it is
now much easier to make performance tests when implementing a new feature.
<dream>
A real killer feature would be to have an application that takes a
project and a source tree, runs all the revisions in master branch and
outputs the times for the revisions in a csv file.
</dream>
Regards,
Marco

Hi,
You may try to use http://sourceforge.net/projects/osm2postgresql/
to test with huge OSM datasets.
I'm doing this daily on continental extracts (and planning to do this on
planet.osm soon). (Do NOT try to import full planet.osm with
osm2postgresql_04.sh, next version will be released soon).
Rendering when zoomed in a lot is OK, but I would not try to zoom out to
much!

I am using some OSM data (osm_administrative in the chart), smaller
areas only for now because I have to repeat each test many time and
work with average to get repeatable results. OSM is very good source
of real data.
I have added PostGIS and SQLite providers and categorized renderer.
Interesting are opposite effects of some commits on PostGIS provider,
e.g. roads_graph-pg-categ x roads_graph-pg-sinsym and also pg x shp,
eg. roads_graph-pg-sinsym x roads_graph-shp-sinsym.
