Per the dixprs website
"Processes:
	* Main program, doing digipeating, message handling, sendin beacon, logging, etc.
	* IS Gateway process, communicating to Internet
	* Radio port handling (independent process for each radio ports)
In a typical system with one radio port there are three running processes."

Lee,

That's interesting, especially the figure for aprx. My
      installation of dixprs (with 3 radio ports, the server and the
      remote database enabled) sits around 33-34% for the main instance
      of dixprs.py. There is four other instances with cpu load =< 1%
      in each case. Maybe they're for each of the radio ports and the
      remote database. Might be worth asking Bela to clarify the
      situation.

                  Have you ever recorded those figures?
