High Performance Configuration for Jetbrains IDEs [IntelliJ, WebStorm, etc..]

Motivation

Once you step into the realm of multi-project development, large scale dev, or just have to have like 6 IDE's open. You really start to feel a performance hit on jetbrains IDEs.

This configuration aims to give at least 10x performance increases across the board.

Goals

• Faster Indexing Times
• More Responsive IntelliSense
• Less random freezing or UI lockups
• Better Memory Management
• More multi-threading
• Quicker startup time

What you need to do

The recommended way of changing the JVM options in the recent product versions is from the Help | Edit Custom VM Options menu. To change the IDE options go to *Help | Edit Custom Properties

For Older IDEs, something like this: vim /Applications/IntelliJ\ IDEA\ 15.app/Contents/bin/idea.vmoptions

• idea.vmoptions --> Help | Edit Custom VM Options menu
• idea.properties --> Help | Edit Custom Properties
