Hello,
according to https://gitlab.com/bitfireAT/davx5-ose/wikis/Roadmap this was solved in v2.4:
according to a user report, “performance with 120 calendars is very bad”
How was this handled? Was this achieved solely by code reorganizarion, or the HTTP queries were changed somehow? E.g. by synchronizing once towards the adreasbook-home-setS/calendar-home-setS, insted of syncheonizing towards each subscribed collection?

Yes. The UI code has been changed from Loaders and ListView to ViewModel and RecyclerView, which is much more performant. Was much work on this never ending project. The next thing is to migrate to the Room database which is almost finished… and then there are about 10.000 enhancements, bugs and minor problems left.
