This is for very bursty logs. You don't log every 7 ns. On average you are not generating a huge amount of logs.

But you need each logging call to be very fast, cause logging calls are usually synchronous.

If the logging call is in the critical path then logging data is probably critical as well. After all, the fastest call is the one you don't do.

If you're writing telemetry then that's different. But if you're using logging to write your telemetry then there are better ways to do it.
