Performance Issues with VScode and Typescript #73470
Comments
Please use this guide to provide more information: https://github.com/Microsoft/vscode/wiki/Performance-Issues. Thanks. |
In fact, this is very difficult to reproduce, I often press F1, then restart the TS Service |
Do you have node-module dependencies? Do you have a rough estimate how many children the node_modules-folder has? |
@jrieken I came here to report the same issue, and I have been able to determine that the slowness does not happen after I remove my node_modules folder. I'm using create-react-app with a few added dependencies so my node_modules folder is pretty large (281Mb) - but uninstalling VS Code 1.33 and installing the Feb release (1.32) fixes my problem. |
@Morphexe Can you share your project? Also, does this reproduce in the latest VS Code insiders build with all extensions disabled? |
Is it likely to be related to this? |
In my case I use styled components withe Typescript 3.3.333 - I had initially suspected styled-components as I have had issues w/ their VS Code extension before. But downgrading VS Code is the easy solution for me |
Closing as more information is needed from the original poster @Morphexe Please test this using the latest VS Code insiders builds (using TS 3.5-insiders) and let us know if you still see this issue |
Issue Type: Bug
I have trouble with vscode, this hapeens quite frequently and after open/close it goes away for a few minutes, sometimes over a couple of hours.
Vscode intellisense and even typings lags like hell, I can see the characters being typing slowly, also its using HUGE ammounts of ram for GPU rendering.
I have caught vscode hogging around 8GB of ram, although it was debugging, but I still feel thats too much.
I can't seem to pin point what exactly is causing this, I have tried without extentions and eventually it all does the same.
Attached is a print of my process explorer where you can see that the GPU process is hogging around 1GB, and so is TSServer. Notice that although I am currently on a surface pro, this happens in my own Desktop which has a 1080GTX and a 16gb Ram with Ryzen 1700. So something else is causing this.
On a side note, the project is not that big, it has around 2000 lines across 20ish files.
Any ideas on how to debug this?
