Hi, it seems that the activation of the extension:GuidedTour (with the dependency) impacts the performance of our wiki installation extremely.
Some times it runs like a charm and sometimes it slows down the entire Wiki.
After some minutes not using the Wiki it takes around 1 minute to load any wiki page (not a guided tour) and afterwards everything is fast hence our suspicion that it has to do with a TTL (time to life) limitation.
Did you experience a similar behavior?
