@pak0st Yep theoretically LTE-M with 1Mbps is sufficient for Audio Streaming / Voice Calls.
But it also depends on the Quality of Service imposed by the Mobile Operator: Dropped Packet Rate, Latency, etc
For Telcos: They will probably use Voice over LTE (VoLTE) on top of LTE-M, which has better QoS:

FYI VoLTE requires only 48 kbps to 128 kbps of bandwidth:

@lupyuen IMHO this article provided an old, boring but cannot-be-wrong conclusion:
the performance (of clone) depends on the actual workload.
The author listed some scenarios they think clone() is better. My knowledge is limited so I can’t comment much. I can say that if the memory-sharing is guarded by terribly designed locks, its performance will be worse than the naive clone() approach

@lupyuen This is very misleading. It highly depends on what you are cloning and how often at runtime (in a hot loop for example?)
Clone while learning or prototyping. Don't get stuck on premature optimization.
But cloning has a performance overhead and you should be aware of that when you want to release your code. Whether that overhead is significant is highly dependent on your specific code.
