IDEA 13.1.4 on OS X 10.9.4 sometimes slow/hangs

Hi,

I'm using IDEA 13.1.4 (135.1230) on OS X 10.9.4 and "sometimes", IDEA consumes 100+ % CPU time and get's slow / hangs for a couple of seconds, mostly during intent actions (option + enter) or during code completion.

Unfortunately there were a couple of environment changes before these problems start to occure:

- Upgrade from 13.1.3 to 13.1.4
- Migration to a new MacBook

I already cleared the cache with no effects.

Does anyone has the same issues? Any ideas or suggestions on how to trace the cause of the problem?

Regards
Stefan
