Overview
The Performance and Scalability working group has a 4 pronged approach for Istio's performance characterization, tracking and improvements:
-
Code level micro-benchmarks
-
Synthetic end-to-end benchmarks across various scenarios
-
Realistic complex app end-to-end benchmarks across various settings
-
Automation to ensure performance doesn't regress
We also aim to provide guidance for sizing and configuration of Istio installation in production and how to ensure scalability.
