[CalendarServer-users] Performance

Hi all! I have a test setup here, and I observe quite a long "calculation time" for report queries. I have some few dates in the calendar, including reccurent dates. It typically takes up to 500ms to give me a time range for 30 days (equals to approx. 30 events) or so. (On a really fast server machine). And for a whole year it takes up seconds... How can I speed up this? What are the performance issues in general? What is this load-balancing thing in the config file? Any help is very much appreciated! (Thanks to Apple having this Calendar Server open source!) Andreas
