Wait, that's like 4.4*10^7 clock cycles for my laptop!

Here's hello.sh (in bash) on a Raspberry Pi 3B+:

  #!/bin/bash
  echo "Hello World!"



  xxxxx@xxxxxxx:~ $ time ./hello.sh
  Hello World!

  real    0m0.010s
  user    0m0.001s
  sys     0m0.010s

Yay, I beat the high score!

Can someone ELI5 why an alternative is really needed here?
