[polly]

Hi,

I've been using Calibre since about version 0.5. I usually update to the newest version each week. About version 1.0 I noticed that Calibre was starting to run more slowly. The problem didn't resolve with newer versions, so I tried uninstalling and going back to a version that had worked for me in the past. Unfortunately, that didn't solve the problem.

Many tasks come with a noticeable lag. Switching from one record to another takes 30 seconds to a minute. Closing the window after downloading metadata can take several minutes, as can opening a book or closing a book within Calibre. The last book that I tried to add (drag and drop) took 35 minutes. Clicking on anything else during the wait makes Calibre grey out and become unstable.

Calibre itself is mostly running normally, until I ask it to do something with a book. I can use the tag browser, search for books, and update metadata without problems, but when I try to select a book or save the changes, it lags again. I does everything that I ask, but it's like trying to run Windows 7 with 1GB of RAM.

I tried checking the library under Library Maintenance and didn't get any errors back. I didn't really expect any, since I have several libraries, all with this problem.

I ran Calibre in debug and went through some of the tasks that lag. The log below is what it spit out. I would welcome any suggestions to solve this.
