Follow these steps to speed up your eclipse as a super fast IDE , it works for 32 & 64 bit version eclipse/jdk on my windows 7 x64. 1.Disable antivirus software, or add your jdk & eclipse & workspace & other related folder to white list in your antivirus software. 2.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.
