Yes - its possible to have it generate the pictures on the first call
of 14all.cgi and that saves a lot of time, especially on the smaller
config files. 

On larger config files, cacheing the configuration parsing (
preferably in a DB but anyway will do ) is needed.  This make it
usable even for non trivial config file sizes ;)
