Just recently I purchased and downloaded your Kalendar 2.1.9 stack and have added it to my RapidWeaver 8.6.2
I have now published a calendar webpage with 6 external calendars of my iCloud calendars.
When the page initially loads, it takes over 15 seconds for the current month to load.
When I move forward or back month by month, it takes approximately 5 seconds for each month change to load.
I find the delay unacceptable and expect my users viewing this online calendar will not be impressed.
Any suggestions as to how to improve the refresh/load times?
