Let’s compare the performance of all supported runtimes + 2 custom runtimes (Rust and GraalVM).
Will compare cold start and warm.
Source code is here: https://github.com/Aleksandr-Filichkin/aws-lambda-runtimes-performance. It requires the minimum local setup(almost all is Dockerized)
- NodeJs (14.x)
- Python (3.9)
- Go(1.x)
- Ruby(2.7)
