Random High CPU Usage

Question

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?

Answer 1

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

Answer 2

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.
