What OS are you running?
I found that if you are running Windows on a single processor/core machine performance of the whole machine is much smoother if you start Calibre via batch file with the /belownormal priority option, and also set the background calibre jobs via the Calibre preferences to run at low priority. As long as you have no heavy foreground tasks Calibre seems as responsive as normal but the machine as a whole is much more responsive when you switch away from Calibre.
Whether you would get a similar benefit on multi processor/core machines I do not know.
