Seems like it's better today, though it was quite slow when I initially accessed it. I think one of the things that was contributing to the perception of slowness is that Calibre gets paged out of 'real' memory to Virtual Memory. It takes a long time to get everything back into real memory, and during that period the UI is extremely sluggish for a good 10-15 seconds. After that adding books is quite slow for the first instance of each input format - the first LRF book I added took 3.6 seconds. Each additional format was similarly slow, but once all the different input plugin code had been 'exercised' everything was back to the speeds I was seeing the yesterday.

I don't recall previous releases being so slow after leaving the program alone for a while. Did something change with the way things are paged in and out of virtual memory?

Memory use was 154 megs, and jumped to 209 after using it a bit, so I don't think any leaks are the culprit.
