Thu, 09 Apr 2026 22:17:59 +0000 https://bugs.horde.org/ticket/6567 webdav performance problem with big calendars 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.

Once we have CalDAV support, this should be much better because it supports atomic operations on single events. Fri, 04 Apr 2008 22:31:03 +0000 https://bugs.horde.org/ticket/6567#t44433
