Each time I start my CDO client its taking up to 3 minutes to load while the first query to the server is run. What I can see when I turn a lot of the debug trace on in the server .options file is that the server seems to be visiting every object that I've stored in the server. The following trace is repeated around 2300 times in the server.log and there seems to be more than one of these for each revision. In this example the name of the object is "Object Map". I've included the TCPSelector trace at the end of the block but I'm not sure if this trace should go before or after the operation shown because its not clear which thread responds to the selection. So my real question is why does my CDO client or the CDO server seems to go over every object and every revision of the object in the DB on startup? It will also occur randomly when accessing objects from the client through the UI but startup is more reproducible and longer.
