High CPU utilization

[laith43d]

Issue Type: Performance Issue

A major performance issue happens all the time, even if I haven't opened a project. It starts just after enabling the extension (GraphQL by Prisma), a process under "extensionHost" called "electron_node server.js" appears which utilizes up to 25% of my Ci7 8750H CPU! My system is an up to date Windows 10 Pro, on the latest Dell XPS 9570 with 32GB RAM.

Extension version: 0.1.6 VS Code version: Code 1.30.1 (dea8705087adb1b5e5ae1d9123278e178656186a, 2018-12-18T18:12:07.165Z) OS version: Windows_NT x64 10.0.17134

I'm having the same problem with Mac OS 10.14.2 on a Macbook Pro 2018 15".

I disabled all my plugins and enabled all after each other to detect that this plugin is the one with the high CPU usage.

@laith43d , @sapkra Thanks for the details and investigation. Are you using the extension on projects with a lot of files? If yes, what is the project size (in terms of number of GraphQL/TS files and size of GraphQL schema) that we are looking at?

[sapkra]

Hey, I executed this command in my project root to count the amount of files with those endings (incl. node_modules).

find . -not -type d | egrep -v '\.ts$' | wc -l
102319

and

find . -not -type d | egrep -v '\.graphql$' | wc -l
106659

But I have to say that my project is at the beginning so it seems like the node_modules have a lot of files.

So I also checked this. I'm using a mono repo so I'll show you the amount of my frontend & backend.

frontend node_modules

ts: 78761 graphql: 80554

backend node_modules

ts: 20609 graphql: 23100

Schema size

And you also wanted the know the size of my schema: it just has 124 lines

@sapkra Thanks for the information, really helpful. I am closing this one in favor of https://github.com/prisma/vscode-graphql/issues/89 as it has more information. Let us use that to track a resolution for this 🙏
