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.
