Apologies if this has been addressed before, but I have been looking at
the Touch CPU load (using 'top') with PCM vs FLAC on 24/96 tracks. 

I searched the forum for the name of the process I'm concerned about
and found nothing, so am posting here.

My Touch is set up with most TT3.0 mods, although not all (vol control
and screen left on but vol at max).  I use analogue out.

With PCM, process sirq-net-rx/0 is running at well over 50% CPU. 
That's a lot.  With FLAC, it's down to around 10-15%.  Total CPU is
around 70-90% with PCM, and 40-60% with FLAC.  I have to admit I am
astonished at how high the CPU load is with PCM.

As I understand it, the theory is that the CPU load needs to be as low
as possible.  Doesn't that imply FLAC is better than PCM, at least at
high bit rates?

If I perform a network diagnostic test on the Touch at 10000kbps, it
seems to be bit perfect.
