This is true of a lot of things.

For example, Mozilla compiles Firefox’s official macOS and Windows builds on Linux because cross-compilation is faster and cheaper than compiling on macOS or Windows in the cloud.

Windows does not fork processes as fast as Linux, although this is improved somewhat in the in the Windows Subsystem for Linux.

Here is a somewhat foolish test with a shell script, that forks "/bin/true" 10 million times.

  C:\>busybox sh
  ~ $ echo 'x=10000000; while [ $x -gt 0 ]; do true; x=$((x-1)); done' > timetest
  ~ $ time sh timetest
  real    0m 46.86s
  user    0m 46.76s
  sys     0m 0.04s

Here is the same test with Debian's dash shell, one of the fastest:

  $ cat timetest
  x=10000000; while [ $x -gt 0 ]; do true; x=$((x-1)); done
  $ time dash timetest
  0m33.79s real     0m33.50s user     0m0.05s system

Not a great test, but there is quite a difference there.

Until one needs to watch YouTube videos.
