Is Visual Studio Code Consuming Too Much Memory and CPU?
If you’re a developer using Visual Studio Code (VSCode) and notice that it’s hogging a significant amount of your system resources, you’re not alone. Many users have reported that VSCode can consume between 60-70% of their CPU and RAM, and this can be particularly concerning for those running systems with 16GB of RAM.
My Experience with Resource Management
In my recent experience, I found that simply launching VSCode with two open tabs—one for my frontend project and another for the backend—was enough to heavily tax my machine’s resources. The moment I attempted to multitask by opening another application, like my web browser, the performance of my computer sharply declined, resulting in noticeable lag.
Why This Happens
High resource consumption by VSCode can be attributed to various factors, including:
-
Extensions: Some extensions can significantly increase memory usage. It’s a good idea to review which ones you have installed and disable or uninstall those that are unnecessary.
-
Workspace Size: If you’re working with large codebases or many files, this can strain your system. Consider optimizing your workspace by closing unused tabs or splitting projects into smaller components.
-
Settings: Certain settings within VSCode might lead to increased resource consumption. For example, features like Autocomplete and Live Share can intensively use CPU and memory.
What Can You Do?
If you find your system slowing down because of VSCode, here are a few tips to manage resource usage:
-
Close Unused Extensions: Regularly check and disable any extensions that you don’t actively use.
-
Optimize Workspace: Keep your workspace clean by minimizing open files and folders.
-
Regular Updates: Ensure that both VSCode and your extensions are up to date, as updates often include performance enhancements.
-
Increase Hardware Capacity: If your workflow consistently requires more resources, it might be time to upgrade your RAM or consider a more powerful machine.
Final Thoughts
Experiencing high CPU and memory usage with VSCode is a common issue, but it’s manageable with a few adjustments. By being proactive about resource management, you can significantly improve your development experience without compromising on performance. Have you experienced similar issues with VSCode?

2 responses to “Is It Normal for VSCode to Use 60-70% of My Memory and CPU?”
It’s not uncommon for Visual Studio Code (VSCode) to consume a significant amount of CPU and memory, especially when handling larger projects or when numerous extensions are installed. However, 60-70% usage may be indicative of potential issues, and there are several factors to consider and steps you can take to optimize performance.
Potential Reasons for High Resource Usage
Extensions: While extensions enhance functionality, they can also drastically increase resource consumption. Some extensions may operate in the background even when not actively used, contributing to performance bottlenecks.
Large Projects with Heavy Files: If your frontend and backend repositories have sizable files or numerous active processes (like live servers or transpilers), this can lead to higher memory and CPU usage.
Background Processes: VSCode sometimes runs background tasks for linting, formatting, indexing, and version control, which can consume considerable resources depending on your project settings and the number of files managed.
Settings and Configuration: Certain settings within VSCode, like enabling all available language servers or auto-save configurations, may add to the load.
Practical Solutions to Optimize Performance
Here are some actionable steps you can take to alleviate the performance hit:
Review and Disable Extensions: Go to the Extensions panel (Ctrl+Shift+X) and disable any that are unnecessary or underused. You can also try running VSCode in the “Extensions Disabled” mode (run
code --disable-extensionsfrom the terminal) to see if performance improves.Check for Large Files: Use the built-in file explorer to identify particularly large files that may be consuming resources when opened. Consider whether these files are essential to keep open.
Adjust Settings: Modify settings to reduce resource demand:
files.watcherExcludeandfiles.excludesettings to avoid tracking files that you don’t work with frequently.If using TypeScript or JavaScript, consider disabling features like automatic type acquisition or reducing
typescript.tsserver.watchOptions.Optimize Your Workspace: If your projects can be divided logically, consider using two separate VSCode windows for frontend and backend development. This can help minimize CPU and memory overhead.
Integrated Terminal Usage: If you are using an integrated terminal for tasks, ensure that it is shut down when not in use, as active processes within the terminal can consume resources.
System Monitoring: Use the built-in Task Manager or third-party applications to monitor specific processes that might be hogging resources. This will help determine if VSCode itself is the only culprit or if other background applications are contributing to the lag.
Increase System Swap: If your physical RAM usage is consistently high, consider increasing the swap space on your operating system. This can provide a buffer when physical RAM is maxed out, helping to prevent system slowdowns.
Conclusion
It’s beneficial to maintain performance in VSCode for a smoother development experience, especially with your current hardware. By reviewing your extensions, tuning your settings, and managing your workspace more effectively, you should be able to mitigate the high resource usage and keep your machine running smoothly even with multiple applications open. If the issue persists despite these adjustments, consider reaching out to the VSCode community or forums for tailored advice or investigating potential system-level improvements.
Thank you for sharing your insights on VSCode’s resource consumption! It’s definitely a common concern among developers, especially those working on larger projects. I’d like to add that another factor contributing to high memory and CPU usage can be the use of certain programming languages and their respective language servers. For instance, TypeScript and Python might consume more resources when utilizing their full language support features.
Furthermore, beyond just disabling unused extensions, consider utilizing the built-in Process Explorer in VSCode (accessible via the Command Palette with `>Developer: Show Logs`) to identify which extensions or processes are consuming the most resources. This can provide a clearer picture of what’s actively taxing your system.
Also, some users have found success with running VSCode in a remote development environment, such as using GitHub Codespaces or setting up a dev container. This offloads the resource strain from your local machine and can help improve performance significantly.
Lastly, one more tip I’d suggest is to explore integrating tools like Docker for project development. This allows for a more isolated development environment, which can help streamline resource usage when managing multiple projects.
