The actual transfer of books is not the problem. Even though I might have a few thousand books on the device, usually only a few of them has been added or have changed metadata and have to be synced.
The problem with many books on the device seems to be the initial connection between the device and Calibre, when info about the contents of the device is gathered and transmitted to Calibre. That process might take a very long time now, if you have a few thousand books on the device. Don't really know why?
