I’ve had some issues with slowness switching tabs in Eclipse 4.2 Juno and was hoping someone might have some answers. The original delay was about 10 seconds which dropped to 2-4 once I specified the java vm in the eclipse.ini file, but that’s still slower than I think it should be. I’ve uninstalled all the addons that I thought might be offending and listed the active ones below and I believe the system to be more than adequate, but listed the specs anyway. Thanks for any help you could give me.

There are some known issues with UI performance in Juno. See the lengthy discussion at https://bugs.eclipse.org/bugs/show_bug.cgi?id=385272
The Juno Service Release 2 (SR2) has been released and it addresses many of the UI performance problems.
