And if you read around you will also see that a typical "low latency"
kernel responds, on average, more slowly than a lightly utilised normal
kernel, because the real-time variant is tuned to provide guaranteed
response times, not the fastest possible.

Secondly, and mainly, as I mentioned above, LMS is forced to wake up and
send a chunk of audio to a player in the range of "several times a
second". The tuning you are talking about is several powers of ten finer
than that. Even a standard kernel gets a clock tick every 1/100th  of a
second so will always get your network packet into your app well before
then next buffer needs to be sent.

This armchair engineer has worked in kernel tuning for decades, and IMHO
you are finessing beyond what is relevant, by several powers of ten.

I restate: LMS does not play audio, it sends asynchronous data to an
audio player in very large chunks.
