Hi Felix,

I saw a well drop down on utilization with 8.4.0 rc but now with final the utilization is as high if not higher than with 8.3.4 ?
Any hints on this ?

blue underline =

And its the same on 4 different installations (all on univention ucs 4.2 errata 209)



It works now as fast as it was with RC Version :)


@externa1 / @fbartels thank you for reporting/fixing this as I was just about to do the same.


Is there an anticipated final release date for WebApp 3.4?
