Fast code is easy. But slow code is equally easy, unless you keep an eye, and measure.
And measuring is hard. This us why consistently fast code is hard.
In any case, adding some crude performance testing into your CI/CD suite, and signaling a problem if a test ran for much longer than it used to, is very helpful at quickly detecting bad performance regressions.
