Yes, so that means Python is slower to start on your system too. Not sure what you mean by "Javascript"... what program are you running?

  Javascriptcore; jsc. It's part of webkit (comes from the webkit2gtk package on my system).

    Oh I see. Cool. Now compare with Lua: $ python3 -c "import sys, timeit; n = 10; print('%.2f ms/spawn' % (1000 * timeit.timeit('subprocess.call([%r, %r], stdin=subprocess.DEVNULL, stdout=subprocess.DEVNULL)' % ('lua', '-'), 'import subprocess', number=n) / n))" 1.09 ms/spawn NewLisp: $ python3 -c "import sys, timeit; n = 10; print('%.2f ms/spawn' % (1000 * timeit.timeit('subprocess.call([%r, %r], stdin=subprocess.DEVNULL, stdout=subprocess.DEVNULL)' % ('newlisp', '-'), 'import subprocess', number=n) / n))" 1.25 ms/spawn
