The implicit assumption in much of the Julia world is that the work being done on the dataset will dwarf the startup time; if your workload takes less than 100ms, it’s probably not worth spending tens of milliseconds on compiling your code in the first place, and you should run it with an interpreter. (Incidentally Julia does support that, but it requires a command-line flag, and can come with a heavy performance penalty if you are running numérica-heavy code)
