Bastard is used in a negative context here :) A snippit of a top
command reveals:
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
3246 root 15 0 2436 2436 1280 S 10.5 3.9 0:14 ices
<p>I am re encoding using:
<encode>
<nominal-bitrate>8000</nominal-bitrate>
<samplerate>11025</samplerate>
<channels>1</channels>
<quality>-1</quality>
</encode>
Seems like its chewing up a lot a cpu cycles or is this by design?

Even worse, you're streaming in managed mode (ABR), which is less than half the speed of the quality-rated VBR modes.
