PhpStorm = Big, Java-based IDE. It's not some simple text editor.

PHP Dev often means some sort of local server running too.

big complex IDEs are almost never compute bound.

compilers are often compute bound (certainly on SSDs).

web servers are almost never compute bound.

[PaulDavisThe1st]

any IDE that is compute bound should be thrown out, especially for a language that is never compiled.

One has to wonder about the carbon footprint of millions of developers running these monstrous IDEs.
