I have lately had trouble using IJ due to performance issues. This is on a Macbook Pro, OS X 10.10.1, 8GB, plenty of available storage space on an SSD. IJ is pretty performant at start-up but fairly quickly things become, for lack of a better word, "sticky": shift-option-arrow to select text may take a second or two seconds to actually move the cursor and highlight the selected text, closing or switching tabs takes a few seconds, random intermittent pinwheel appearances, no response to mouse clicks, etc.
I work this machine fairly hard, running a VM and IJ, Outlook, iTerm with tmux sessions, and plenty of other utilities and the like. So I don't expect it to fly like lightning. But not that long ago it was much better and I'm wondering if it's a matter of the 14.0.2 release and/or the bundled JDK or what the heck's going on.
One thing I notice that I haven't seen before (doesn't mean it wasn't there)... when I "run ps ax | fgrep IntelliJ", the things you'd expect all show: idea, fsnotifier, and a big fat process that is basically the bundled JDK running the main IntelliJ app. But there's another one that basically comes down to this:
java org.jetbrains.jps.cmdline.Launcher org.jetbrains.jps.cmdline.BuildMain
Is that new?
Anyway, I don't have anything to pin my performance issues on IJ other than the issues seem to have started sometime around the time I updated to 14.0.2. Has anyone else observed this sort of issue?
