Speed up your Eclipse or FlashBuilder as a super fast IDE
1. Disable unecessary validations and startup action in eclipse reference.
For validations: on eclipse menu Windows -> Preferences -> Validation, click “Disable All”, and then select the validator which you need. I selected “Classpath Dependency Validator” only.
For startup action: on eclipse menu Windows -> Preferences, type “startup”, select “Startup and Shutdown”, untick the options you don’t need. (Thanks for David’s suggest, I’ve added the above 2 detail steps for readers)
2. Modify eclipse.ini to set the Xmn(new generation size), Xms and Xmx, enable parallel GC
