This is how calendar publishing over WebDAV works, unfortunately. Once we have CalDAV support, this should be much better because it supports atomic operations on single events.

I would like to implement a horde/kronolith solution for allowing my Linux users to connect to a calendaring server using sunbird/lightning. I widely tested it and it works very well, except for users having very big calendar (more than 2000 entries) when they just add or modify something. I tried everything to improve performance (using memecache for instance) with no success. When I watch the horde.log , it seems that the whole username.ics is "reinjected" in the mysql database, not only what were modified, thus having a 30s delay for each modified, deleted or created.event I don't know if i'm wrong. If not, I don't know if it's feasable to enhance it. Thank you.
