[Qgis-developer] Benchmarking / optimization

[Andreas Neumann]

 I can confirm that performance in a production environment is ok - see 
 examples at http://gis.uster.ch/

 Performance can always be improved, but one also has to keep in mind 
 that the other two projects (UMN and Geoserver) are specifically 
 programmed as a map server whereas QGIS server was originally only 
 Desktop and is quite a bit younger in development history.

 The benchmarks also had some quite extreme examples that are not always 
 common in production environments. But it is good to participate in 
 these benchmarks to find and detect issues that can lead to performance 
 improvements.
