I think the query about how you measure CPU usage is valid.

I'm running MythTV 0.22 under Ubuntu 9.10 on a Dell Latitude D810 (1.8Mhz
Cemtrino, 1.5Gb RAM)
It's got an external monitor as well as the builtin screen so I can monitor
he CPU using atop without disturbing the frontend.

Initially frontend.real used about 14% while backend used about 3%. After a
few minutes, the frontend usage dropped to 0% while the backend stays about
the same (maybe drops to 2% or even 1%). The only other non-zero process in
mysqld at 1% (sometimes). Apart from the odd spike in backend use (to 100% n
the hour) it's been like that for over 10 minutes now.

How are other people measuring the CPU usage?
