Description

PyPerf doesn't seem to account for PEP659's dynamic interpreter optimising the byte codes in the target function.

There is a condition for PyPy and GraalPython to run a warmup cycle, but not for Python 3.11+. I know PEP659 isn't a JIT, but functions which are heavily optimised will be unstable.

Can some flag be set to run a warmup cycle?

Research direction

Start by reading the existing warmup-cycle condition for PyPy and GraalPython, then trace how benchmark options are exposed and applied. Determine how a warmup flag should cover Python 3.11+ PEP 659 specialization, and verify that benchmarks using it produce stable results.
