Yes, that's something that's on my list for this cycle fwiw.

Since this is only audio, I wonder how many packets per second this is? 50-100
packets per second or so should not have such a huge impact really, even on a
low-powered machine.

If we hit the kernel with futex syscalls that means there's a lot of contention
on some locks (which is not unexpected for the jitterbuffer I suppose, with one
thread pushing packets in and another pushing them out?).
