Can we get a little better performance? (Score: 2, Interesting) by email@example.com on 2014-08-23 20:46 (#410) On a middle-aged machine (a little low on CPU but plenty of RAM), Calibre can take up to two MINUTES to start. It can take equally long to load a 1mb PDF or a 500k epub. (It does somewhat better on .mobi files.) When I go to page down, it often stalls for up to half a minute. I like the fact that it's capable of handling so many file formats, but lordy, the patience it's extracted from me in return... Re: Can we get a little better performance?

(Score: 1) by email@example.com on 2014-08-28 05:04 (#2R1X) This is a lowly P4-2GHz with 1.3GB RAM and WinXP. Everything else runs fine (sufficiently well that I'm not terribly motivated to replace it); Calibre is notably sloggy. I don't put =any= books in its library, and occasionally I clean out the trash it leaves in %Temp%.The bookmark script frequently hangs, too: "A script on this page is running slowly. Do you wish to stop the script? Yes/No" and once it does that, the script will never complete and will sometimes crash the whole program. If it's done it once on a given book, it will do it again in that same part of the file, tho I haven't pinned down a common factor, other than it's more likely with larger files.
