I upgraded from IntelliJ IDEA from 12 CE to 13 CE few days ago and it has been hogging up CPU. Every few minutes it'll peak to 450-500% and then come down to 100-200%. Also, I've upgraded my Scala plugin to 0.30.380. Not sure what's causing the issue!?

I have frequent issues with my laptop fans going 100% and other tasks freezing because IntelliJ uses almost 100% of the CPU to reindex, to build the project. Even on small projects.
High CPU usage can be indicative of several different problems. If a program is eating up your entire processor, there's a good chance that it's not behaving properly. A maxed-out CPU is also a sign of a virus or adware infection, which should be addressed immediately.
IntelliJ IDEA memory usage Follow IntelliJ itself reports that it is using a little more than 1GB of heap but the OS reports that it is using anywhere from 3.5 to 4.5 GB.
I'm posting this comment by K P as an answer, because K P does not have enough reputation.
It just needed some more memory to prevent repeated garbage collection. I found the file idea.vmoptions [aka idea64.exe.vmoptions] and increased the memory for InteiiJ to run (Xms = 512m and Xmx = 2048). The CPU usage has come down to 0.2 - 10% when nothing is being done on it.
