I have an FE playing on a notebook computer. It's currently playing a
movie as well.
 PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND  
20   0 3424m 535m  56m R   56 26.9 517:12.52
mythfrontend.re                                             

On my atom netbook, which is idle:
20   0  585492  99916  40200 S   6.3  9.9 109:33.51 mythfrontend.re

I'd check top and even try htop to see what is chewing up resources.
Myth doesn't use up *that* much horsepower.
