[Speed] option in performance to invoke number of worker preocess

[Victor Stinner]

There is a --fast option to spawn less processes:

But I don't suggest you to use it since it's less reliable ;-)

For me, it's really important to get stable benchmarks:
http://pyperformance.readthedocs.io/usage.html#how-to-get-stable-benchmarks

Most benchmarks can be run a standalone scripts: see
performance/benchmarks/ in the source code (performance.benchmarks
module). These scripts provide the full perf CLI, all options:
