Yeah, this resonates. I have a high end machine (9950x, 64 GB RAM, and a 5090) and Webstorm is PAINFULLY slow.

I don't use any crazy plugins and I hit one or more of these issues almost every day:

  - Code analysis during git commit taking minutes
  - 10-15 seconds for the as-you-type suggestion box to pop up, I often end up just typing the full variable name myself
  - Typescript taking 10-30 seconds to refresh errors, even with the experimental tsgo rewrite
  - Freezing and displaying the "dump threads" message, weirdly also lagging out my Spotify
  - Easily consuming 10+ GB of memory (how?)

My daily ritual is restarting Webstorm from how much memory it leaked overnight.

Many of us still use Jetbrains products because we're willing to put up with a little lag for the multitude of really useful features you get, but they need to attack performance seriously or they're going to risk losing folks.
