I prefer to run Eclipse with a minimum 1 GB of RAM. I have experienced JVM crashes in the past using Eclipse with MyEclipse, an issue I solved by increasing my min/max setup memory settings (see: Eclipse startup memory settings ).
If you find Eclipse sluggish consider implementing the following tips:
- Increase your min/max memory settings (see above link for more info) from 40/256 to 256/512 or higher. You might have to experiment with the min/max setting but increasing the initial memory heap to 128 when Eclipse starts should help.
- Disable the code folding feature (e.g., auto-hiding of import statements). Go to
Eclipse > Preferences > Java > Editor > Foldingand uncheck "Enable Folding" checkbox. - Disable Code Assist Auto-Activation. This means no more code assist popups when you type "." to invoke a list of class method/properties. Go to
Eclipse > Preferences > Java > Editor > Code Assistand uncheck Auto-Activation checkbox. - If you are using MyEclipse's plugins you might consider disabling (temporarily until you get more memory) it's many validators
Eclipse > Preferences > MyEclipse > Validation. The DTD, HTML, JSP, XML validators all use up memory and can slow the system down.
