Delayed audio transmission #20

I've complied Barnard using Golang 1.6.2 on a Raspberry Pi Zero ARM6 @ 1GHz.
All works well. Audio is received perfectly with minimal latency, but transmitting audio is delayed several seconds.
Running Top I see CPU usage is above 90% when running Barnard in transmit mode. When not transmitting the CPU is around 4%. When receiving only, CPU is around 25%.
I assume the high CPU when transmitting is due to audio compression and encryption which is therefore causing the long delay.
I am willing to sacrifice compression and/or encryption to get the CPU usage down.
Is this doable? And will this solve my problem?

did you solve this problem ? i have same problem with raspberry pi 3. delay is increasing over time.

I wasn't able to get it to work and haven't been able to dig into it again. If you can fix it, I'd love to find out how you did it.
