WebStorm hogging CPU even when idle
I am using webstorm with a node.js project.
The project is big, but not unreasonably big.
From time to time webstorm becomes very slow up to unresponsive.
I notice that webstorm takes lots of CPU (40%-50% is very typical).
I have a reasonably powerful machine.
This must be a setting thing (watchers?), I find that when idle (just have a few files open), even when I scroll up-down in a file, cpu usage can go up to 20% easy.
When typing in a single character into a file (for example a backspace), cpu usage jumps to 40-50% for several seconds.
What is this?
Please don't ask me to just take snapshots because it is a lot of work, and last time you could not deduct anything from that.
Thanks,
Ilan

If you aren't going to provide snapshots, the only thing I can suggest is excluding node-modules from indexing. This can only be done in WebStorm 9 EAP (doesn't work in WebStorm 8);
How do I take a snapshot?
How to capture the CPU snapshot:
start the snapshot, type something, make some actions in IDE(at least for a minute), then stop the snapshot: https://intellij-support.jetbrains.com/entries/29983118 .
