Yes, you can tediously pick through the default settings and try and turn unnecessary processes off -- but that gets beyond the ability of many users (do I need this process, or can I turn it off?) I turn off everything non-necessary for my desktop, and even then Plasma smokes the fans on my 5 year old laptop. So unless you need desktop effects, fading windows, fonts that auto-size for your windows, etc... you may want to consider a different desktop.
My guess is that if you remove small processes, the main process will simply use the full remaining power, so no gain. Instead, you can use tools like cpulimit to limit the cpu power of the main process. If it is a daemon, systemd can help. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
