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.

Hi Luca
Benchmarks are very specific, it's impossible to create general
statements just from the slides without knowing the test arrangement
very well.
If you are referring to the foss4g benchmark this year, the first
comparison test was mainly about the performance of near empty
requests (otherwise, impossible to handle more than 100 requests per
second also for umn or geoserver).
In production environments, my impression is that QGIS server is not
dramatically slower than other WMS servers.

In a recent WMS comparison presentation (MapServer vs GeoServer vs
QGIS server vs others), benchmarks had shown that QGIS server is the
worst and doesn't scale with the number of CPU cores.
