How on earth would POSIX define performance of something like pipes?

I was addressing "it's all posix and given it's all in memory the performance will be more or less the same."

Not claiming that POSIX should or could attempt to address performance.

By using Big O notation, or deadlines like on RTOS APIs, as two possible examples on how to express performance on a standard.

Some standards do define performance requirements, e.g. operations on data structures, in BigO notation.
