Hmm, the only point where Tellico is noticably slow for me is at 
 startup (collection of ~2k books, most with front-cover images) - if
 I have the front-cover column visible, it takes about 2 minutes from
 starting until they're displayed:
real    2m0.283s
user    1m30.360s
sys     0m1.996s

*If* that time is spent creating thumbnails, caching those on disk 
 might speed up startup significantly.

Machine is pretty beefy (4GHz AMD FX8350, 8GB RAM), Tellico 
 2.3.5+dfsg.1-4 on Debian/amd64.

(Also, I'm seeing lots of 
    tellico(32636) Tellico::Data::Image::outputFormat: writing "GIF" as PNG 
    tellico(32636) Tellico::Data::Image::Image: "/tmp/kde-$user/tellicoH7kGNf/e5b57818e730b9ee9eabcfc89e0d5e9e.gif" loaded as PNG image 
 in the console, which might not be intentional.)

cheers,
