When using the AI agent, both the CPU and GPU were highly occupied

[trigger-cn]

When I was using the AI agent, both the CPU and GPU were extremely occupied, causing the computer to become extremely sluggish.

My computer runs Windows 10 system, and I also have a Ubuntu 24.10 VMware virtual machine installed.

And, I use the cursor ssh to access my virtual machine and carry out code development.

My windows computer：

Processor: 11th Gen Intel(R) Core™ i7-11700 @ 2.50GHz (2.50 GHz)
RAM capacity: 32.0 GB (31.7 GB available)
Storage: 932 GB HDD WDC WD10EZEX-75WN4A1, 1.86 TB SSD Netac NVMe SSD 2TB
Graphics card: Intel(R) UHD Graphics 750 (128 MB)
System type: 64-bit operating system, based on x64 processor

Hey, thanks for the report. This looks like an issue with the extension host restarting while it processes project files over an SSH connection.

I’ll need a bit more info:

• What Cursor version are you on? (Help > About Cursor)
• About how many files are in the project you have open?
• What extensions do you have installed? (especially Python, if you’re working with Python)

In the meantime, please try:

1. Test without extensions: run Cursor.exe --disable-extensions and see if anything changes
2. Create a .cursorignore in the project root:

   **/__pycache__
   **/node_modules
   **/.git
   **/venv
   **/*.pyc
   

3. Process Explorer: press Ctrl+Shift+P → “Developer: Open Process Explorer” and check which process is using resources (extensionHost, ptyHost, or something else)

We’re working on optimizing the extension host for large projects, but for now this is a known issue. SSH + VMware can make it worse.
