MobileRead Forums - View Single Post - 0.7 -- Sending metadata to device is SSSSLLLOOOOOOOOOOW

Calibre 0.7, Mac OS X 10.6.3, Mac Pro Quad-core Xeon 2.8GHz, Sony PRS-700.

When I send books to my Reader, Calibre updates the metadata on the device. That's great! The problem is that with 400-ish books on the device it takes...

wait for it...

10 minutes for the update to complete. And the update runs automatically each time I add or remove books from the reader. If the update can be sped up, that would be super. If not, can it at least be deferred until I finish deleting and downloading books?

For most of those 10 minutes Calibre is consuming 100% of the CPU on one of my four cores. A quick sampling of the application suggests that nearly all of that time is spent messing around with xml files somehow (e.g., I saw an awful lot of XMLpathxxx entries in the profile data).

What further information can I provide to help diagnose the problem? I'm happy to provide further data as needed.
