Description

« Hide

The cursor freezes and the app hangs temporarily whenever I do any type of refactoring and often at other random times. I have increased the memory and it isn't using all of the memory but is hanging anyway. It is almost unusable. The same project in Eclipse is very fast.

Could you please take a CPU snapshot of an editing operation that is slow? In order to do so, please add the following line:
-agentlib:yjpagent
to idea.exe.vmoptions and restart IDEA. Then you'll get a button "Capture CPU snapshot" on the toolbar. Press the button, perform some operations which are slow, and press the button again. Then attach the generated file to this JIRA request.

I changed a variable type by typing over the existing type and then renamed a variable using refactoring. Both operations caused a short freeze.

Thanks for the snapshot! As a workaround, please switch the Project toolwindow from "Packages" to "Project" view.
