Typescript (deno), Python and Go. Tbh the goal is really not to compete with AWS Lambda on performance as they use microvm with hot http servers, but to show that it's not order of magnitudes slower.
Yeah usually the slow part with Lambda is either them loading your container/runtime... or for a long time the P99 on getting the ENI attached into your VPC for vpc lambdas when they have to get a new worker host. They brought that way down and it used to be P90 of like 100ms but p99.9 of something like 17s. I believe that's basically fixed now.
But yeah if you're showing your comparable or same ballpark the criteria is less crucial. Was mainly just adding addtional data. Good luck on the project. A light framework like this for essentially scripts locally without kube or heavy docker is nice.
