You might want to reconsider "freebusyd", which solved that exact
problem for years now: https://roundup.kolab.org/issue2554

After we introduced freebusyd, updating the freebusy data
was never an issue again.

Freebusyd + caching of the Horde Kolab classes easily handles
updates to calendars with 10.000 events in no time at all.
