Profiling is the nice, cozy, and lazy way to efficiency. There's something neat
about avoiding optimization and having the numbers to prove it relative to an
initial baseline. In [PHP](https://www.php.net/) there's
[Xdebug](https://xdebug.org/) and
[KCachegrind](https://kcachegrind.github.io/html/Home.html) and I recently saw
[`php-spx`](https://github.com/NoiseByNorthwest/php-spx#readme) in my feeds. A
profiler in any language environment with snapshots of performance over time is
just --- well nice. The terribad situation is not understanding exactly how
something became slow. It might be too late then.
