Re: Calibre memory leak & slowdown when updating metadata

I finally had chance to try this on another machine running Win7 x64 (4Gb)
(first machine was Win7 32bit SP1, 2.5Gb)
DEP for essential windows programs & services only
Antivirus disabled

Ran it against 800 books.

Same behavior - time to update metadata was roughly the same as the count phase (> 10 min)

Calibre memory usage climbed to almost 400Mb.

Ran ExtractISBN.
Extract phase about the same (>10 min), metadata update phase about 45 sec.

So there's something different about the metadata update procedure this plugin is using.

Of course after a few more tests I won't have any reason to count big batches again, so with a little patience and remembering to restart Calibre to clear the memory leak I'm good to go
