I’m getting 70mops byId and 23mops qs-#id. This looks like making a huge difference until I add these cases:

  3: "abc”.replace("a", "b")
  4: "1" * 2

Which result in 15mops and 74mops respectively. This test measures diameters of neutrinos so to say.

My experience is that most developers tend to guess at performance and throw away numbers they disagree with. As a result performance testing is only something product owners care about.
