[mythtv-users] using ionice on commflagging

[Jerome Yuzyk]

[First off, thanks very much to those who have responded to other questions 
I've had. I don't feel right spraying the list with just a Thank You, and a 
faulty mouse button caused me to over-delete some queued threads for 
questions I asked.]

Is anyone using  ionice  for commflagging? I Googled and read some discussion 
of it but nothing unequivocal enough to keep me from asking the list. My TV 
box seems to struggle when I watch a recorded program while others are 
commflagging, especially during the watermark-finding phase at the beginning 
of flagging, and when more than one commflag job is running. I only hit about 
50% CPU (already niced-d) during that, but I think it's disk priority that's 
getting me - my machine has a single consumer-grade PATA IDE drive that I 
have hdparm-ed for best performance. I get pauses in playback and skip-ahead 
as the commflag seems to suck up disk attention, even though my CPU still has 
headroom. Even with only 1 job running I can tell when it's in the initial 
phase.

Thanks!
