These processes are doing the real job - reading the config files,
creating the html pages and graphs.

The first think might be the problem: parsing the config file takes time.
Tobi had an idea how to speed it up but I have to make sure that the
config file gets parsed again if it changes.

My problem is to find the time to do this ...

It creates files with the extension ".cache".
