[Roberto Marzocchi]

Yes. You are right! 

Sorry today I'm particularly stunned.
 If you need a project for test here you can find this project

exactly. when checking this, I assume all the slowdown is due to Lizmap
requesting GetCappabilities even before loading layers, which in case of
many WMSs slows down considerably initial loading of the project.
Cheers.
