VS Code Performance Issue: Freezing and Not Responding

Is your Visual Studio Code (VS Code) acting up, freezing, or just generally not responding? You're not alone! This article dives into a specific performance issue reported in VS Code version 1.105.1, extension version 0.32.4, running on Windows 10. We'll break down the problem, analyze the provided system information, and discuss potential solutions to get your VS Code back on track.

Understanding the Problem

The core issue is that VS Code is not responding, indicating a significant performance issue. The user is experiencing freezes or hangs, making it difficult or impossible to work. To effectively troubleshoot, we need to examine the provided system and process information.

System Information Breakdown

Let's dissect the system information to identify potential bottlenecks:

  • CPUs: 13th Gen Intel(R) Core(TM) i5-13420H (12 x 2611) - This is a decent processor with 12 cores, so CPU performance is unlikely to be the primary issue unless a specific process is hogging resources.
  • GPU Status: The GPU status shows various features enabled, which is generally good. However, direct_rendering_display_compositor: disabled_off_ok might be worth investigating further if display-related issues are suspected.
  • Memory (System): 15.71GB (1.04GB free) - Having only 1.04GB of free memory could be a contributing factor. VS Code, along with other applications and background processes, might be pushing the system to its memory limit, leading to performance degradation. When memory runs low, the operating system starts using the hard drive as virtual memory, which is much slower and can cause significant slowdowns. It's like trying to run a marathon with ankle weights – possible, but definitely not efficient!

Process Information Analysis

The process information provides a snapshot of resource usage by different VS Code processes and related extensions.

  • code: The main VS Code process is consuming a relatively small amount of CPU and memory.
  • extension-host: This process hosts extensions, and in this case, it's using a significant amount of memory (935 MB). This is a key area to investigate, as a problematic extension can easily drag down VS Code's performance. Think of it like having a messy roommate who leaves their stuff everywhere – it can make the whole house feel cluttered and slow.
  • pty-host: This is related to the integrated terminal. If you're using the terminal heavily, it could contribute to the issue.
  • window: This process represents the VS Code window itself and its associated editor instances. Its memory usage (422 MB) is also worth noting, especially if you have many files open or complex editors.
  • Powershell: Multiple instances running, related to terminal shell integration. It is a normal behaviour, but if you're not using the terminal, it is a clue.

Workspace Information

The workspace information reveals the project structure:

  • Folder (HighLitapi): 26 files, mostly Python files. This seems like a reasonably sized project, so the project size itself is unlikely to be the primary cause of the performance issue.

A/B Experiments

This section details active A/B tests in VS Code. While these experiments could potentially influence performance, it's less likely to be the direct cause unless a specific experiment is known to have issues.

Potential Causes and Solutions

Based on the information above, here's a breakdown of potential causes and corresponding solutions:

  1. Extension Issues: The high memory usage of the extension-host process strongly suggests a problematic extension. This is the most likely culprit. Here's what you can do:

    • Disable Extensions: Disable extensions one by one (or in groups) to see if performance improves. Start with recently installed or updated extensions. This is like detective work – you're trying to identify the suspect that's causing all the trouble.
    • Identify the Culprit: After disabling an extension, restart VS Code. If the issue resolves, you've found the problematic extension! Consider updating it, replacing it with an alternative, or simply disabling it permanently. If you are using ms-python.python extension, try to update it. Consider disabling Jedi if enabled. Then restart VS Code.
    • Extension Settings: Some extensions have configurable settings that can impact performance. Check the settings of your installed extensions and adjust them if necessary. For example, an extension that performs intensive code analysis might have settings to control the frequency or scope of the analysis.

  2. Memory Pressure: With only 1GB of free memory, your system might be struggling. Here's how to alleviate memory pressure:

    • Close Unnecessary Applications: Close any applications you're not actively using to free up memory. It is a good practice to have only the applications you are using.
    • Increase Virtual Memory (Page File): Ensure your system has adequate virtual memory (page file) configured. This allows Windows to use disk space as an extension of RAM when physical memory is full. Be careful setting the size, Windows has a default configuration that usually works well.
    • Upgrade RAM: If you consistently experience memory issues, consider upgrading your system's RAM. It is a great boost to your computer's performance.

  3. Terminal Usage: If you're using the integrated terminal extensively, it could be contributing to the problem.

    • Limit Terminal Instances: Avoid having too many terminal instances open simultaneously.
    • Use External Terminal: Consider using an external terminal application (like PowerShell or Command Prompt) instead of the integrated terminal.

  4. VS Code Configuration: While less likely, VS Code's configuration itself could be a factor.

    • Disable Unnecessary Features: Review your VS Code settings and disable any features you don't need. For example, if you're not using breadcrumbs, disable them.
    • Reset Settings: As a last resort, you can try resetting VS Code to its default settings. This will remove any customizations you've made, but it can sometimes resolve unexpected issues. Back up your settings first!

  5. Underlying System Issues: There's a small chance the issue stems from a deeper system problem.

    • Check for Malware: Run a full system scan with your antivirus software to rule out malware infections.
    • Update Drivers: Ensure your graphics drivers are up to date.
    • Check Disk Health: Verify the health of your hard drive or SSD.

Troubleshooting Steps

Here's a suggested approach to troubleshoot the problem:

  1. Restart VS Code: Start with the obvious. Sometimes a simple restart can resolve temporary glitches.
  2. Disable Extensions: Disable all extensions and see if the problem goes away. If it does, re-enable them one by one to identify the culprit.
  3. Monitor Resource Usage: Use Task Manager (Windows) to monitor CPU, memory, and disk usage while using VS Code. This can help pinpoint which processes are consuming the most resources.
  4. Check VS Code Logs: VS Code has logs that can provide valuable clues about errors or performance issues. You can access the logs through the
