I am running a late 2009 Macbook with OS X Mountain Lion 10.8.1 and Calibre 0.8.66. I have several large (200-300 MB) PDF files. When I perform the simple function of changing their title from the "Edit Metadata" window, Calibre hangs for 1-2 minutes while performing the update.

I also find Calibre to run very slow generally-- it takes a long time to load up and there is a significant lag when after clicking almost any button. When compared with the similar library management functionality in Papers2 (an OS X PDF manager), the difference is night and day. Calibre has been well reviewed on Mac Appstorm and I've seen it recommended several other places as well. There also seems to be no alternative on OS X. I can't imagine that it is normal for Calibre to run as slow as it does on my machine. Anyone know what would make it so slow?
