My question is, is it worse or better with Ruby,NodeJS, Perl,Java or Go? I remember NodeJS scripts being extremely slow to start in general, way slower than Pyt

  Sorted from slowest to fastest: (all single measurements on my Arch Linux notebook) $ time java &> /dev/null java &> /dev/null 0,09s user 0,03s system 120% cpu 0,102 total $ time ruby -e 42 ruby -e 42 0,04s user 0,01s system 99% cpu 0,053 total $ time python -c 42 python -c 42 0,03s user 0,00s system 98% cpu 0,030 total $ time perl -e 42 perl -e 42 0,00s user 0,00s system 92% cpu 0,005 total I don't have NodeJS at hand to test with. Note that Java produces a help message (which I sent to /dev/null), but that (hopefully) shouldn't affect the timing that much. Go produces compiled binaries and, as such, exhibits no such startup delay. Startup times for Go programs that I tested are in the same ballpark as Perl above, i.e. not reasonably measureable with a millisecond-precision tool like time(1).
