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?
