One of the massive benefits for Rust on Lambda is (as the author mentions) "extremely low start-up time, CPU usage and memory footprint". It's not clear to me if deploying Rust to Lambda via a docker image actually negates some of those benefits. | ||

Using Lambda functions stored in ECR has no impact on performance from my experience. AWS Lambda uses Firecracker under the hood, which builds a VM from a container image. It's likely that non-ECR image based Lambdas are actually packaged as a container image before being launched into a Firecracker VM. https://aws.amazon.com/blogs/aws/firecracker-lightweight-vir... | ||

Good question! I ran some benchmarks before because I was also curious and besides some slightly larger standard deviation for cold starts execution time, there was so significant difference in performance when using docker. | ||
