Faster Eclipse IDE

Some tips and tricks to speedup Eclipse IDE, or at least slim it.

These may be useful when you have hundreds of Eclipse projects (literally).

(

UPDATED: as of Eclipse 3.7 (Indigo), I would recommend Spring Tool Suite (STS) over Eclipse EE, it’s a custom Eclipse build but more well-tested, at least no issue with common plugins.

Startup VM options

via eclipse.ini (STS: STS.ini)

No verify VM option:

-Xverify:none

or

-noverify

 

Heap memory VM option: increase max heap size

-Xmx1536m

sometimes increase min heap size

-Xms256m

 

Eclipse settings

 

Validation: Windows -> Preferences -> Validation

Uncheck some validations on “Build” such as: DTD, EJB, WS-I, XSL, …

 

Plug-ins at startup: Window -> Preferences -> General -> Startup and shutdown

Turn off unnecessary plugins, such as: Eclipse automated error reporting, Mylin team UI, …

 

Maven (m2e): Window -> Preferences -> Maven

Turn off “Update Maven projects on startup“, “Update Maven projects on startup“.
