I wonder if you do have a bad file or have corrupted one of the databases. I have 650+ books on my 950 and only 125MB of free space on the internal memory. I just transferred over 13 new books assigned to multiple collections using the Sony Reader Library auto-sync feature. Once I disconnected the USB cable, I timed how long it took to load my home screen. Only 1 minute 35 seconds.
EDIT: By the way, I have 3 periodical series, 26 collections and 205 notes at the moment.
