Clippy is a huge cause of CPU usage, as it checks the contents of the clipboard every 500ms (i.e. twice per second). This has been fixed in git.
The issue, however, is somewhere else, as this is the output from "top" after around 18 days of uptime (but I could have killed plank 11 days ago and relaunched it) with 1 Docklet ("Show Desktop"; no Clippy, Trashcan, Clock, ...) and 6 application launchers (Firefox, Thunar, Simple Scan, Libre Office Writer, XFCE Terminal, VLC):
