For example, if I hit CTRL+SPACE or some other auto-completion feature, the whole IDE locks up for 10 seconds or so (often more). When the editor restarts inspecting the code (after a short idle period), it just seems to get stuck (the editor remains available but the inspection takes a very long time).
I'm working on very simple Groovy scripts in this sort of case, no more than say two screenfuls of pretty straightforward code, in projects with about 5 source files and no fancy metaobject protocol stuff going on, no external libraries, etc., and I'm using a fairly recent Windows XP machine with 2GB of memory and no other memory-hog processes.
It's getting to the point where I'm having to "unlearn" the productivity features of IDEA just for the plugin to remain usable!!! If it comes to that, I might as well use a plain text editor...
Is there something that can be done to improve this?
