<p>Sounds like an interesting idea.  Several people have wandered into #vorbis
asking about this because they were curious how much CPU they needed to be
able to encode for streaming.

<p>Does this mean that oggenc should periodically load big chunks of the PCM data
from disk into memory?  Or would benchmarkers really want an oggenc flag that
forces it to preload the whole WAV into memory and buffer all of the Vorbis
output until the end?
