Random High CPU Usage

I have noticed that Visual Studio Code randomly has a really high CPU usage. Generally, this seems to be related to the window where I have a SQL server project. Below is the output from code --status when this recently happened. Any insights into what might be going on here?

first you need to find which process eating your cpu, for that vscode has inbuilt process Explorer. You can find at Help => Open Process Explorer

For me the culprit is electron_node tsserver.js, I solved it by turning on the typescript.disableAutomaticTypeAcquisition, for that you need to go Settings => Extensions => TypeScript and check the Typescript: disable Automatic Type Acquisition

I had the same issue today.

First I removed Php intelliSese Extension and my cpu usage came down to around 25%. Then I removed Vetur extension for Vuejs (I don't remember how or when I installed this), and now everything is running normal and cool.

Hopefully it helps you too.

I was also facing a similar problem with my VS Code. It was consuming huge amounts of power(HIGH) and also lots of CPU resources. For me, I was running a JavaScript application; So I guess, after selecting the Typescript: disable automatic type Acquisition it worked for me and there was a significant improvement!

Even if you observe that your laptop is getting heated abnormally while using VS Code, you should try one of the approaches mentioned by others here!

Today my Visual Studio Code was draining my CPU and this happened after I had created a big bunch of files (6GB each of which being a couple of KB). I moved the files outside the scope of the editor and everything worked fine. I guess some extension or the editor itself was having a hard time indexing the files.

I hope this could help.

I have the same problem after I installed C/C++ extension in VScode. I think it is the VScode's bug. After I uninstalled this extension the high cpu problem was solved.

I have the same problem when I import my whole user directory, e.g. /home/usr/ into visual code and eventually crashed my system. I resolved it by selecting specific working directory, e.g. /home/usr/Documents/work, and adding subsequent folders when needed. Then, my CPU usage back to normal

Its probably some extension. For me it was IntelliSense. Disable them one by one to check.

Try to increase the Max TS Server Memory.

  • press "F1"
  • choose "Preferences: Open Settings (UI)"
  • search "Max TS Server Memory"
  • change to something higher like 6000 (mine was 3072)

saw here: https://github.com/microsoft/TypeScript/issues/38329

I did not want to disable TSServer because it helps with autocomplete, imports, etc.

I had the same issue where just typing into my JS project would cause my CPU use to skyrocket to 100% and when I stopped typing it would settle down at 12%. This was infuriating because it would cause everything else to hang, including the video player on Udemy.

So I decided to apply all the advice I found in this thread to my own issue but the issue still persisted. So I decided to disable my extensions one by one to see if that solved the issue.

Funnily enough, it was GitHub's own "GitHub Pull Requests and Issues" extension that caused my issue. Disabling it dropped my CPU usage from 100% to around 40%, which was a start!

As another user mentioned, try disabling your extensions methodically to see if that alleviates the issue.

I was also faced with this problem even my vs code was taking almost between 60% to 70% of CPU and also with memory usage. I have faced this problem for 1 month. I tried to reinstall another version of vs code more than 4-5 times. and also tried to disable some extensions. but nothing happened. the problem was that I had already installed a lot of extensions and added different projects to the workspace. This works for me when I removed unused projects folders from the workspace without disabling or uninstalling the extensions.

Faced same problem but in my case whas the PHP extension pack for Xdebug. I have disable that package and CPU under 10% again :D

user_19345320

For me, Typescript, PHP extension pack for Xdebug, C/C++ extension, PHP Intellisense are not responsible for 100% CPU usage.

I disabled all the extensions but no luck.

I found that my Data folder of VSCode had not enough writable permission. After correcting permission, it is fine even after enabling all the extensions.
