Remote server development slow to a halt over time

Seems this question is still waiting to be solved in latest 0.45.2 ? Thanks for any reminder.

I’ve tested the exact same setup with cursor and vscode and only cursor seems to be having these problems. For me it will just hang in the "Reconnecting to… "loop at some point, so I have to reload the window, which is pretty annoying at some point, especially if there have been large changes after the reconnection failure that do not get captured and are gone after the reload.

hey? since 4 month I’m looking for people who have the same issue than me,
sometimes, I can code for 30min and it’s all smooth, and sometimes, after 10min, it’s super slow even if I got 32go ram, and a I5 CPU.

I can’t even click on a function, open a folder which contain files, save files, everything is super slow, my mouse is slow etc, on vs code I try to code for hours, and nothing wrong, when I close cursor my mouse come back smooth etc

cursor have a issue but I don’t know what,why, how.

When this is super slow, I try to refresh then I got “cursor reloading the window is taking a bit longer” like for 30sec sometimes, then an error popup window happened with error reloading, close, reopen, etc

Since the first day I use cursor this is happened, in 7 hours work I need to reload 10-20 times cursor, copilot doesn’t work because this is so slow, chat is lagging, navigate in files is lagging.

Hey, can you try run the Open Process Explorer command when you witness one of these slowdowns, and see if anything sticks out there? It’s possible an extension you use is poorly coded, and is slowly eating away at your resources as you code!

I’ve run that and not seen anything particularly concerning. I dont think the CPU column actually works, it shows all zeros and the memory column is using max 188MB. Ubuntu 22.04. Weird performance as well, sometimes no worries, but today it is unusable.

Anything that doesn’t show there isn’t triggered by us directly, so I’d assume an extension is running some kind of sub-process that is causing the issues.

Unfortunately, this isn’t something Cursor may be able to get much visibility on. I’d recommend trying to figure out which if any of your extensions are causing this!

I dont think so. The remote doesnt have any extensions installed, and it I got a sweet small amount of time this morning when it worked well. Restarting it doesnt help at all which is weird. It grinds to a total halt. Im also a pro customer, I’m probably going to cancel. I literally cant edit a line of code on linux.

edit: cancelled - people are busy, they dont want to spend time troubleshooting the tools they expect to work so they can get on with the things they need to do. Responded to your automated email, happy to continue the convo if we see some reasonable support.

Sorry we couldn’t get a solution for you, we want to dedicate more time to remote ssh, and hope to do so soon. I totally get the frustration - when dev tools don’t work reliably it really impacts productivity. Thanks for giving Cursor a shot and for the detailed feedback, it helps us understand where we need to focus our efforts

Same issue here with Cursor on Windows when connecting over ssh to an Ubuntu machine on my LAN. It gets painstakingly slow after a while, then eventually crashes with an OOM error:

It has done this about 4x in the past 5 hours, no matter which model I am using. Both the windows machine (I9-10850k,64GB ram) and ubuntu machine (R9 5900X, 128GB) are fast enough, are otherwise idle cpu-wise, and have ample free ram available when this happens.

I hope this gets fixed soon.

I’m experiencing a similar issue.
When I check the execution time with the cursor server, it takes a huge ~18 seconds.
If I force the cursor server to shut down and then run the same command, it only takes ~0.3 seconds.
This is a terrible situation for anyone using SSH!



It seems serious problem, is there any plan to update it? @danperks

Hi @ppeey,

Can you open a new bug report and @ me in it, as this is quite an old thread?

Thanks
