I don’t have any head-to-head comparisons of the same app written in both languages. I can compare apps with similar functionality: listening to GitHub web hooks vs. Linear web hooks. Both are deployed to Kubernetes.

The GitHub listener written in Go has a CPU limit of 50m, but actual usage of 10m. Memory consumption is around 34MB of a 64MB limit.

The Linear listener written in Typescript consumes around 20m/250m CPU, but 235MB/500MB memory.

The 2x CPU and 9-10x memory consumption is significant, especially as we scale usage or add services.

(Yes, I know we need to do more right-sizing.)
