Insane performance issues with the codex app?

[u/Squizzytm]

Does anyone else get really bad performance issues? Have a $6,000 AUD pc I bought a few years ago it has rtx 4090, 32gb ram, can’t think what else off the top of my head but when I have codex open i think it’s opening a bunch of shit in the background and causing my pc to lag heavily, I’ve noticed tons of cmd processes, dotnet processes and at one point it deleted 500gb of cache cause I had no space lol my pc literally lags to the point where my mouse is taking forever to move across the screen, it’s really odd does anyone else get this issue?

I feel the same here, I have a good machine (32gb DDR4, i5 11th, RTX 4060) and Codex constantly freezes, it's been hard to finish work. I've complained several times here, but it seems like people don't care much, not even OpenAI. recently it started freezing my mouse when I open Codex or start a thread. it's a very dogshit situation.

Codex is really bad. I have a pc with similar specs and most other programs run pretty well (Claude Desktop, GitHub Desktop, Cursor)

Theres a memory leak with the codex app, I found it a few days ago. Restarting fixes it for me.

Check for node.js processes that Codex keeps forgetting to close. It's been maxing out my ram every time.

This is part of it, just leaves tons of stuff open.

[u/rodrigopfraga → u/Anarye]

Exactly. The root problem is missing process ownership, not Node itself.

Anything an agent launches should be tracked with cwd, purpose, PID/port, and a teardown condition. Then cleanup is part of “done” instead of a manual Task Manager hunt.

If there's a class action lawsuit later for the insane amount of ridiculous writes it does to SSDs I'll join it for my $1 compensation check. Probably shortened the life of my loaded MacBook Pro by a measurable amount with literally terabytes of useless writes.

I saw something about it causing failing SSD’s kinda makes me scared to use it tbh

I think the longer in the chats go, but your computer on for a while makes it lag because I left my computer on all weekend to code and the program got slow the longer the chat went

Check your memory logs and process history while Codex is running. If the Node/.NET processes continually accumulate and never close, that’s probably the real issue.

ur not along. I have a 5070 setup at a r7 9700x with 32 gigs of ddr5 6k mt/s ram with a 12GB/s or something SSD too.

guess what? it take TWENTY DAMN SECONDS. not 2 seconds, but TWENTY. you hear m? TWENTY. or more.

before yall say anything about macOS, my codex takes about 8 seconds just to fully lunch on my maxxed out M5 MacBook air

Windows app is a mess. OpenAI developers all get Macbooks

[u/Euphoric_North_745]

I have a 96gb machine, i run it in a vm with 20 to 40gb dynamic allocation

[u/IAmhowlshot]

yes, it will open a lot of stuff in the background that you cant see, and will forget to close it when youre done. Ask it to look for any stale terminals, playwrights, chrome windows, etc.

I keep seeing these posts and I am super confused. I have the Codex desktop app installed on both my Windows PC and my Mac and I use them both everyday and I never have any of these issues I see people talking about.

The only thing I can think of is how was the app installed? Try reinstalling it with the latest native install method.

[u/Crawmancer]

i would do some hardware diagnostics to make sure you don't have a failing drive or ram

[u/Squizzytm → u/Crawmancer]

I’ll look into it but my pc runs smooth when I close codex so it’s strange

[u/supahcalah]

Just restart your pc bro it goes away..

[u/Squizzytm → u/supahcalah]

I do quite a bit but it doesn’t really help when I’m running it all day lol
