Cursors take up a lot of memory

[Mrdapeng (0x1fad)]

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.

Normally, Cursor would use about 1GB of memory when that project is open.

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.

Hi @dizengoff

Try this:

Cursor hogging memory (?)

Hi @Viswa4599 Yes, large projects use a lot of memory, both in VS Code and Cursor, but try checking the processes by opening the command palette and searching for “process explorer”.

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!

Now the IDE is very slow for me!
What is the cursor helper and how to limit it?

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