A while ago I wrote an AWS lambda runtime to use Racket. I saw terrible Startup performance at around 500ms for a simple echo program.

  Yeah, reading all those parentheses on startup is not fast. As an anecdote, I used to host a computationally expensive web app written in Racket (even before Chez version) serving large amount of requests at peak times on a single $10 DigitalOcean droplet. It was pretty fast and didn't crash. No need for awkward modern web scale thingies.

    Is the parentheses comment a joke?
    • dchest 3y ago
      Yes :) I don't think there are many of them in a simple echo program, and I guess the runtime is compiled when it's shipped.

  Are you aware of AWS lambda warm starts? Start-up time can be less critical should the lambda be used frequently enough. https://docs.aws.amazon.com/lambda/latest/operatorguide/execution-environments.html https://docs.aws.amazon.com/lambda/latest/operatorguide/exec...
