No, we did not. Our stack is still on the grow but we're starting to run into the same problem.
That said, we have many small files, so I'm pretty certain that for us, setting up gulp to always only recompile whichever file changed (which we currently don't do) should be good enough. Afaik there's ways to do this with gulp but I did not investigate yet.
Do you guys manage to only recompile changed files?
Thanks for the WebStorm hint! Did not know that!
