afaik AWS doesn't publish benchmarks on runtimes; but if they did, I am sure it'd result in a lot of finger-pointing and wasted energy if they were not to normalize the process first (something like acidtests.org).

For ex, see Chapter 9: Optimizing serverless application performance of their well-architected series: https://aws.amazon.com/ru/blogs/compute/building-well-architected-serverless-applications-introduction/ https://aws.amazon.com/ru/blogs/compute/building-well-archit...
