IDEA 11.0.1 Maxes Out CPUs During Indexing

Awhile back (v10.0?), I lamented how long indexing was taking, noting that my desktop's 12 CPUs and notebook's 8 CPUs never exceeded a utilization of ~5%.

Today, I installed 11.0.1 (build #IU-111.167) and the indexing option used a lot more than 5% of my notebook's 8 CPUs - in fact, it maxed out most of the CPUs most of the time!

Here's a TaskMgr snapshot when it was only taking 67% (but I've watched it go to 95%+):





And here's the snapshot of the CPU Meter:



My IDEA64.exe.vmoptions are slightly changed from the install:

-Xms256m
-Xmx2048m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=64m
-ea

I hated to see IDEA take too long indexing because it was using too little CPU. But I also hate losing almost all usability in my system because IDEA is consuming nearly 100% of CPU while indexing.

I know I'm being a little picky here, but can't there be a happy medium? Is there a way to configure IDEA to choose that happy medium? I'd like to make it use more than 5%, but less than 75% of CPU, while indexing so I can get other work done during indexing.

Thanks.
