Hey All,

I'm new to the forums and to calibre as well, having just installed it yesterday. Since then, i've been having trouble with excessive cpu utilization every time I use the application.

For instance, importing arouind one hundred files, (including pdfs, docs, rtf and lits) took over an hour and the cpu usage was at max during this entire time.

Also if i just click from one title to another it can utilize anywhere from 60-90% of my cpu, scrolling does the same.

Is it normal that it is this sluggish? and a cpu hog? From the lack of many post concerning this problem i'd have to think no. So i'm wondering if it is something to do with my computer config.

To that extent, i've disabled my Anti-virus (Avast) and killed all non-essential processes running and tried calibre, but its the same problem. (I never have any indexing programs running without consent.)

I've noticed that the mem usage can reach ~500,000k, which is half of my total physical mem, when the app window is selected. Currently it is over 200,000k and it hasn't been the selected app for at least 10 minutes.

In general the app runs sluggish and is not very responsive, i assume it is due to the cpu issue.

As for drivers, i keep them pretty up to date. For instance, i can play Dragons Age with no video or sound issues.

Does anyone have a solution or a suggestion? It would be appreciated as this app, aside from the problem i'm having, seems to be pretty nice, and would be immensely useful if it operated correctly.

My system specs are listed below:
