It astounds me how much I hear about the “VSCode extension uses all my CPU” thing.

Yes, the extension uses a ton of CPU for 15 minutes the first time you set it up. It’s building a giant database for type information to give you type checking and hints.

It does this ONE TIME when you first set it up. It explains this. It’s really not a big deal. I’ve found the extension to be great, I’m not really sure what you are referring to there.

It isn't just "ONE TIME" for me. The extension freezes up often and completely stops giving autosuggestions or warnings, and the only way to fix it is to delete the .elixir_ls file and rebuild the database. When I say "often", I mean there are some days where I have to do that at least once an hour, and 5-15 minutes of high CPU usage every hour is just way too much to be acceptable.

I love Elixir and the ElixirLS extension is the best I've found so far, but that's not saying much. The extension has enough issues with it to make it very frustrating to work with, and even enough to make the entire Elixir experience not worth it in many cases.

Is it possible to share more details about your particular setup? I believe you, but this doesn't sound right. I've used the plugin on all three major operating systems in a wide variety of projects and configurations, and have never had this happen to me. Curious to learn more about what could be the culprit for you.

I have had the same issue as the parent poster. I'm on Windows 10. Everything was fine when I was on Elixir 1.9.2, but the moment I upgraded to 1.11.2, the ElixirLS extension just started to break frequently, or getting stuck while building. I ended up disabling it until I have time to troubleshoot further.
