I also am frustrated by the extreme slowness of Calibre because I like the tool for what it is. The main issue for me is that the UI very unresponsive and the tool in general is rather unstable.

For example, simply bringing up the Preferences dialog box takes way longer than it should. Navigating the Preferences dialog is also slow.

I have tried running it on both a Windows 7 machine (8x cores, dual raid, 8 gig ram) and a super cheap Ubuntu laptop. The specs of the machine are irrelevant and performance is poor on both.

Also, do not tell me to disable my virus checker. That's insulting.

Don’t even ask me to describe the performance of ebook-viewer. Its appalling. I would rather have it launch an external program that is half decent at displaying ebooks (ie: fbreader or anything else).

I did some testing and renamed the images folder in my resources folder and the app ran MUCH faster. Who uses svg files for toolbar icons? That's crazy!

I suspect the tool needs to undergo a serious optimization pass as up until now its performance has been rather unacceptable.
