[mythtv-users] best method to performance tune?

[Risto Treksler]

this info could be used to auto-tune myth-tv settings

i mean mythtv could look at 
cpu speed 
amount of ram
hardware mjpeg acceleration
free disk space on the system
etc.
and auto tune itself 
if it had access to this info

all the user would have to do is fine tune
