[pulseaudio-discuss] Less CPU overhead with a new protocol channel mechanism

this is indeed a relevant problem; PA easily uses 20%+ CPU on 
embedded ARM systems in low-latency duplex workloads according to my 
measurements

I'm somewhere in between 1 and 2; I'd like to reproduce your 
measurements on ARM
