My assumption is that this is garbage collection (watch the heap indicator on the bottom right part of the screen).
If these pauses are not acceptable to you, you can play with the garbage collection parameters See the sun performance FAQ (http://java.sun.com/docs/hotspot/) for more information on this. If your computer is fast enough, try the -Xincgc flag. This will cause more frequent garbage collections, but reduce the long pauses. Be careful, though, because this does reduce over-all throughput. What I think is happeneing, is that the young generation size is too small. So IDEA generates a lot of short-lived objects. These objects very quickly get promoted to the old generation (even though they will not last long), and that requires a full GC (long pause) to fix. Try increasing the size of the young generation relative to the old generation. Also increase the size of EDEN. Ideally, our intellij friends would run through these experiments, and change the .bat file to use an appropriate set of VM arguments (or at least create a number of "options" in the BAT file that would be potential candidates for different classes of machines).
