phpstorm PhpStorm optimization Speed increase using OpenGL
Example
PhpStorm can be very slow in large files as its performing so many inspections. One quick and easy way to speed up PhpStorm is to render using OpenGL. Previously in a 5000 line file it would give the 'eye' symbol in the top right for a long time before changing to a tick (or red/yellow box). After OpenGL it does this almost immediately.
To enable OpenGL:
Open: path-to-phpstorm\bin\PhpStorm64.exe.vmoptions
Then add these two lines below the others:
-Dawt.useSystemAAFontSettings=lcd
-Dawt.java2d.opengl=true
