I've been using WebStorm for a little over a year, and although it's much more helpful than atom/sublime, it does tend to drag every now and again.

Do you have any tips on optimizing performance for your dev environment? It's a shame using webstorm in power save mode.

Switching between projects dragged a bit; I recently switched everything to a monorepo (https://github.com/twitter/commons/tree/master/src/bash/git/...) and now start the IDE from the repo root. Snappy now.

Also exclude node_modules, logs.

I often end up marking node_modules as "excluded", which sucks a bit for autocomplete/intellisense style code insights, but really speeds things up. Switching branches seems to be the primary thing that grinds it to a halt.

If you have the RAM to spare, you can up the [JVM allocations](https://www.jetbrains.com/idea/help/increasing-memory-heap.h...). The setup instructions should be adaptable to other IntelliJ based products.

I remove plugins I don't use - that might help.

Also, as other people have mentioned, "exclude" files from being watched by the editor. I do a lot of NLP and machine learning work and I often have very large text training files in my working repos - important to tell the editor to not to watch these files.

Switched to the All Product pack also. 2nd year was supposed to be free if paid yearly but my account page states next billing will be in 2016.

Did you notice if the "Next billing on " date on your JetBrains account page was wrong?

I noticed the same thing.

thanks for the confirmation.

What plugin do you use for Haskell?

I use the Haskell plugin from Jetbrains - it is the one with the most downloads. Then open a project that uses stack, create an execution target. Under the "Before launch:" area, add an external tools target: stack build --exec <project name>

That lets me run from the IDE. Syntax hiliting and formatting works well.

I've seen a lot of people recommend Haskforce: https://carymrobbins.github.io/intellij-haskforce/

Do you work for Jetbrains?

No.
