yeah, but your claim was "Note also that Julia would be number 1 in almost all of those benchmarks if you were to rank by speed of second run"

notice this isn't even a language vs language benchmark. it's libraries and frameworks.

plus I don't think even the author of the julia library in question would agree with your statement: https://discourse.julialang.org/t/the-state-of-dataframes-jl...

as mentioned in that thread, GC and strings, or especially a combination of the two, can be very much a downer in terms of julia performance. That's actually pretty surprising since strings are often as important if not more important than numbers for a lot of data processing needs.

I'd also say in terms of compilation time, some autocaching layer outside of precompilation would do wonders.
