Hi Oliver, It seems to be core slide issue so it would be there even if we plan to use just slide api and not webdav client, isn't it? Also it would be irrespective of store type file or db,isn't it? Is this problem related to locking and transactions? Currently we are seeing response times of around 3 secs for checkin ( this is the slowest of all actions) with 200 users. Can we do any tuning of slie params to increase performance. If you could give some insight, it would help us. Thanks, r.d Oliver Zeigermann <[EMAIL PROTECTED]> wrote: Well, this is "somewhat" fixed in 2.1. The first beta is to be expected in August.
