I'm seeing poor performance during recording. I also noticed that there are many many mythtranscode processes running (or, one with lots of threads) and there are plenty of messages in the backend log saying "Waited 4 seconds for data to become available, waiting again...". I found where this is logged in RingBuffer.cpp but I'm not sure about the cause besides the obvious point that the mutex isn't getting unlocked fast enough.
It makes sense that mythtranscode should be running as I have real-time commercial flagging enabled but I don't see why there are so many processes/threads active.
The machine is running the current debian package, not sure what svn version that is. The only other data point is that I did a dist upgrade at the same time as upgrading myth. I wonder if there's some sort of library mismatch. I'm going to try building packages from source to see if that helps.
