Cursor IDE is slow as ... (unworkable)

Discussion

Lately the Cursor IDE is almost unresponsive.
It is the app in itself that doesn’t respond, not the LLM response.

  • restarted my laptop
  • closed the cursor IDE
  • made sure all commits are done

but still very slow.

I see that the following memory consumption:

  • cursor 4.3 GB
  • cursor helper 6 GB
  • Docker 11 GB
  • python 2 GB

I have another set up where I don’t use docker, but even then the cursor IDE is slow.

with a laptop of 16 gb, very likely this is due to memory swapping.
anybody any suggestions for this (besides buying a more beefed one).

Hey, sorry to hear you are having some issues here.

Can you try running the Process Explorer, and checking what is using up so much memory? It’s possible an extension is using up a lot of RAM, which is causing the slowdown.

Thanks that helps to keep an eye on the resource eating parts.
I think the main issue is during the build process with the docker images, eating up memory and disk space. regular starting new chats and restarting the IDE, and keeping other apps closed, helped a lot.
Thanks again for the insights.

Same thing over here: it’s impossible to work. The UI is really slow.
I’ve checked the Process Explorer, working with Flutter and a Simulator. Just the main cursor window process takes almost everything of the CPU and then goes down a bit and then the cycle repeats. I didn’t change anything of my normal workflow.

The AI feature is great, the IDE literally is killing my CHI. Often not responding for up to 30 seconds. This occurs regularly more often than not. On top of that claude frequently stops responding and the app crashes multiple times per day. The usefulness is not lost on me but how this can be sold as a professional “non beta” product is a mystery that I will never understand
