Comment on Show HN: Kern – container and resource runtime in a 1.5 MB binary, no daemonparentComments−realexwebOP17dImage already pulled: 3.7 ms for the box, and a shell command adds nothing on top (3.73 vs 3.71 over 100 runs, alpine).Python is 15.6 ms in a python:3.12-slim box, but ~12 of that is CPython starting, which you pay on bare metal too.Cold cache is a different order: the pull dominates and is network bound. Alpine 2.7 s, python:3.12-slim 9.0 s for 41 MB, once.
