Testing on my machine, Hello World in java (openjdk 21) takes about 30ms.

In contrast, "time" reports that rust takes 1ms, which is the limit of it's precision.

Python does Hello World in just 8ms, despite not having a separate AOT compilation step.

The general guidance I've seen for interaction is that things start to feel laggy at 100ms; so 30ms isn't a dealbreaker, but throwing a third of your time budget at the baseline runtime cost is a pretty steep ask.

If you want to use the application as a short lived component in a larger system, than 30ms on every invocation can be a massive cost.
