how OpenFaaS handles concurrent requests in the function？

[wiluen]

I develop a python code for image process, when i send lots of request to the function, I can see many "forking fprocess" in logs, it can handle many request concurrently, but my python code don't use any "async", Whether OpenFaaS framework provides the ability for functions to process requests concurrently？
