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?

[Corion]: Has anybody toyed around with Mastodon? There is a Perl module for it, but I'm not sure that it's a yak worth chasing
[Corion]: On the upside, maybe running that for my family would be interesting, or at least for myself
[Corion]: I'm not fond of using a server hosted by other people, even if they claim to be GNU ;)
