Performance tests

Knative performance tests are tests geared towards producing useful performance metrics of the knative system. As such they can choose to take a blackbox point-of-view of the system and use it just like an end-user might see it. They can also go more whiteboxy to narrow down the components under test.

Load Generator

Knative uses vegeta to generate HTTP load. It can be configured to generate load at a predefined rate. Officially it supports constant rate and sine rate, but if you want to generate load at a different rate, you can write your own pacer by implementing Pacer interface. Custom pacer implementations used in Knative tests are under pacers.

Benchmarking

Knative uses mako for benchmarking. It provides a set of tools for metrics data storage, charting, statistical aggregation and performance regression analysis. To use it to create a benchmark for Knative and run it continuously, please refer to Benchmarks.md.
