Combined FE/BE. Commflags run low priority, and mythbackend doesn't take
much cpu, but the frontend has become a disaster. Right now I'm watching a
hidef stream ('Cops' off fox) and its chunky, with hesitations/skips every
5-15 seconds. Nothing else going on (no recording, no jobs).
In .18 I could commflag hidef in realtime, so it only ever had one job at a
time.. now its 2-3x realtime (and it gets worse since it ends up flagging 2
shows at a time.)
Its not IO bound (or doesn't seem to be):
Cpu(s): 52.5% us, 41.9% sy, 0.0% ni, 5.6% id, 0.0% wa, 0.0% hi, 0.0% si
