Re: [Qgis-developer] Testing/Master renders 7times slower than 2.2
Hi Anita I am a bit late to join the discussion, but anyway... I cannot really replicate the slowness you are experiencing. I can see some slowdown which I assume is mainly related to the labeling - in 2.4 there have been some changes that will likely slow down labeling even more - e.g. checking of validity of polygons (due to issues with invalid polygons from simplification) and the subsequent fixing with buffer. For a good comparison, I would suggest to have a look where the slowness really comes from. Apart from labeling, there could be many more factors affecting the speed - data-defined symbology, expressions in rule-based renderer, used symbol layers, reprojections etc. Generally speaking, we should try to handle the performance regressions more seriously - in the process of adding new features it is easy to introduce something that negatively affects the rendering speed. Radim has done some effort to build a benchmarking system for QGIS some time ago, maybe it is time to bring it back to life and start watching it more closely. Btw. nice project for testing purposes. The multipolygons layer contains a bunch of invalid geometries, it helped to find bugs in some of the new features :-) Regards Martin On Sun, Jun 1, 2014 at 7:49 PM, Anita Graser wrote: > Hi, > > I have a project with Spatialite and Shapefile layers and I found that > it's around 7times slower to render in the current test version than > in 2.2. > > The project is online, so you can try it yourself: > https://drive.google.com/folderview?id=0Bwc-5JFVTnfIZkZOM3Y0Um9jOHc&usp=sharing > > I've tried different rendering options including parallel rendering > but found no way to improve the rendering speed in Testing. > > I'd love to know if it's a general problem or if I have misconfigured > something. > > Best wishes, > Anita > ___ > Qgis-developer mailing list > Qgis-developer@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/qgis-developer ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Testing/Master renders 7times slower than 2.2
I've delved a little bit further into the matter: Anita's original project is a 2.2 project. If you convert the project to version 2.4 by simply saving it and then open the new version 2.4 project the time to open it is reduced to 6.0 sec. Every time. So the delays is due to QGIS 2.3 opening a version 2.2 project.

Re: [Qgis-developer] Testing/Master renders 7times slower than 2.2
Hi Anita -
I've just tried your project on my win8 pc with QGIS 2.3 32 bit and
compared it with my QGIS 2.0 set-up on the same pc:
Start-up times for the "annecy" project (QGIS already started with an
empty project):
* QGIS 2.0: 6.7 sec. every time.
* QGIS 2.3: 1. time 6.9 sec.; 2. time: 7.5 sec.; 3. time: 8.4 sec.
7. time: 11.9 sec. I've loaded an empty project between each
iteration.
It takes between 0.6 - 0.9 sec. longer for each reload of the project.
If I restart QGIS and load the "annecy" project the load time falls to
6.9 sec. again.
The QGIS Code revision number is ca6d4d9.

[Qgis-developer] Testing/Master renders 7times slower than 2.2
Hi, I have a project with Spatialite and Shapefile layers and I found that it's around 7times slower to render in the current test version than in 2.2. The project is online, so you can try it yourself: https://drive.google.com/folderview?id=0Bwc-5JFVTnfIZkZOM3Y0Um9jOHc&usp=sharing I've tried different rendering options including parallel rendering but found no way to improve the rendering speed in Testing. I'd love to know if it's a general problem or if I have misconfigured something.
