How to speed up WebStorm

Here is my recipe how to speed up your lovely WebStorm:

• Go to Preferences and do next:
  1. Appearance & Behaviour > System Settings > Updates: disable auto update
  2. Appearance & Behaviour > System Settings > Usage Statistics: Uncheck Allow sending data usage statistics to JetBrains
  3. Editor > Live Templates: disable all, leave only what you are really use
  4. Editor > Emmet: disable all emmets
  5. Editor > Intentions: I leave only: CSS, Declaration, JavaScript and Language Injection
  6. Plugins: leave only next (* - can be also disabled in case you don't need them):
     • CoffeeScript *
     • CSS Suport
     • CVS Integration
     • Git Integration
     • HTML Tool
     • IntelliLang
     • JavaScript Debugger *
     • JavaScript Intention Power Pack
     • JavaScript Support
     • NodeJS *
     • Perforce Integration
     • SASS suport *
  7. Project > Directories: Exclude all what you don't use
  8. Languages & Frameworks > JavaScript > Libraries: leave only: HTML and HTML5 / EcmaScript 5
  9. Languages & Frameworks > Compass: disable it
  10. Tools > WebBrowsers: leave only Chrome

• Help > Edit Custom VM Options: Edit and increase usage memory pwd:

  -Xms1024m
  -Xmx1536m
  -XX:MaxPermSize=1024m
  -XX:ReservedCodeCacheSize=512m
  -XX:+UseCompressedOops
  

So the main idea is next: disable all in Preferences what you really don't use and increase memory for IDE.

There is a "Power Save Mode" setting in the files menu. This will disable some syntax highlighting and stuff, but will improve the speed of any JetBrains IDE.

Also check out ScriptedAlchemy's jetbrains-ide-performance github repository - and be sure to check out the updated settings in the issues. Disabling unused global symbols (search for it in the settings, it's under inspections) also seems to help.
