How does the performance of Intellij IDEA compare with the PhpStorm Lightweight IDE?
I've always been impressed with the blazing fast responsiveness of the rich features, debugging, and intellisense in PhpStorm. I understand the PhpStorm features are pretty much the same in IntelliJ IDEA, with exception to Open Directory Project Creation.
Assuming this is the case, I'd really like to know whether or not IntelliJ IDEA manages I/O, memory and CPU utilization as well as PhpStorm. In other words, will I be just as happy with the responsiveness of IntelliJ IDEA when working on PHP development projects?
