FEATURE REQUEST

What happened:

Trying load testing the python runtime produces very low results.
E.g. runtime nodejs gives much better results .

Tool for tests: Locust
Number of concurrent Locust users: 10
The rate per second in which users are spawned: 10

Results:
Python:

Avg RPS: 80

Nodejs:

Avg RPS: 230

What you expected to happen:
Functions with Python runtime will have similar perf like Nodejs

How to reproduce it (as minimally and precisely as possible):
Simply function hello-world

Environment:

• Kubernetes version (use kubectl version):
  Server Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.7", GitCommit:"1dd5338295409edcfff11505e7bb246f0d325d15", GitTreeState:"clean", BuildDate:"2021-01-13T13:15:20Z", GoVersion:"go1.15.5", Compiler:"gc", Platform:"linux/amd64"}
