in thread replace / with \ using regular expressions?

You need the tr/// operator

No, you don't need it. TIMTOWTDI, and s///g is as understandable and easy to write just like tr///.

The difference in performance is impressive

But typically completely irrelevant for the performance of scripts/programs of any size. This optimization feels pretty immature.

When will doing 287356 of these operations per second ever be anything other than fast enough?

marto wonders what fresh hell the firefox update has brought, apart from maxing out CPUs
1nickt was looking into Firefox Extended Support releases yesterday. You don't have to go with the updates!

[LanX]: FF has become a source of instability :(
[1nickt]: erix not so wonderful for the lungs :-(
[erix]: the stuff is pretty high up as I understand it; I have not felt any effect on lungs/breathing
