There are no complicated operations. Just opening the project takes up a lot of memory.

in my case was a plugin which tool the cpu to 99% and I was almost able to cook an egg on the macbook surface.

Hi @mouratoglou Is your project large? If so, I experienced the same issue in VSCode.

I just got this for the first time after using Composer. It finished and gave me the results, but a few minutes later, the memory kept increasing, and it basically froze my PC. Running Cursor 0.42.2. [Screenshot 2024-10-15 141233] Normally, Cursor would use about 1GB of memory when that project i…

Likewise, I’m seeing enormous memory usage. I have a project in python using Quart. Typically sits around 80-90% memory and CPU usage and often crashes. Makes it very difficult to build or fix issues. [Screen Shot 2024-10-23 at 4.48.10 PM]

Turns out, the real culprit behind the memory overload was the chat itself! After some digging, I found a game-changing fix—compressing all the project files into a new folder and reopening it as a fresh project. And just like that… Boom! It worked like magic! :rocket::sparkles:

Now the IDE is very slow for me! What is the cursor helper and how to limit it? [screenshot-20250316-065335]

4 gb memory usage since couple of days. too much.
