Hi Jan,
The performance tests are maintained and augmented at occasions. Lastly 
we added authentic data for a EU project we are involved in.
We should probably move the pointer for data.exist-db.org to another 
host. Thanks for pointing this out.
We also use the xqts in conjunction with the unit and performance tests. 
The xqts tests are run with a larger time cycle frame than the unit 
tests on our build server though.

The utilisation graphs for the different build clients can in some way 
also be used to to see how the performance is affected by every build.

Cheers,
Leif-Jöran
