PhpStorm is a fantastic editor. Unfortunately it can be quite slow. Brent, one of our developers at Spatie, blogged a few tips to make it run a bit faster. I've followed all his suggestions and PhpStorm now feels a bit more responsive.
I didn't start this post by writing my own thoughts, because I figured people were looking for some quick tips to speed of their IDE. As a PHP developer, I think that PhpStorm is such a powerful tool, which helps me to write good and maintainable code. I don't want it to stand in my way though, so good performance is an absolute requirement.
Hopefully future versions of PhpStorm will be more performant out of the box.
