Codex app on Windows became extremely slow today even in /fast mode

In this reply, the poster is criticizing what they see as a logical misrepresentation: they say that “suggested” is not the same as “they’re aware”, and invoking the principle of identity means that a thing should be treated as exactly what it is, not as something slightly different. In other words, they are accusing the other person of changing the meaning of the original statement and asking for more precision and fairness in wording. The tone is frustrated and sarcastic, but the core point is about sticking to the exact meaning of terms in logic and discussion.

Sorry for the confusion! OpenAI is aware of the situation and pointed out that it already had a status page… in Codex CLI. That’s when @VeitB suggested adding a Codex App category too.

Apologies for not being more clear! :slight_smile:

Oh, man, you needed help from an AI model to clarify that?! Uhhh… humanity is lost.

And, @PaulBellow , do not be so shy with you - it’s not about “more clear” , it’s about being or pretty dump or manipulative.

Or, to make it sound nice, it’s about not paying a minimum attention to the first of the 3 pillars of the rationality - if you cannot handle principle of identity, what can you handle?!

Even the AI models cannot understand that principle of identity: it’s not about “same thing” , it’s about the “identity of the thing” which is unique, ma’ friend. “Same thing” can be more - same things. But identity is unique.

I’m not sure if this is exactly the same bug, but Codex on Mac started going very slow and taking tens of seconds to switch threads. It finally occurred to me that this issue started after I added a project to Codex with a very large amount of small files.

Same slowness here ,please do something about it

Seems like it, just stuck at thinking…

Codex stuck every where vscode, codex ios. Please fix asap. Don’t know whom to tag.

This is a different problem that has not been resolved.

You are welcome to report issues on this forum.

The official place to report issues is the GitHub Open Codex issues tab.

The stuck at thinking issue has been reported several times.

Today, on March 10-11, 2026, it is incredibly buggy and laggy.

The mitigation is Implemented seems to have worked on me, I currently do not have delay anymore what so ever (or atleast does not feel like it)

Hi, this issue has been resolved as posted on our status page: https://status.openai.com/incidents/01KK9JA8JKQKDW1W24T09NHBYH

Let us know if you are still experiencing slowness.

I’m not sure if this is the same issue but today I tested Codex app for Windows for the first time and when I prompt it with a basic prompt like “explore this repo” it takes about ten minutes before it appears to do anything, then it spawns a dedicated subagent for reading one file each and they also lag badly. At that point I stopped it. It doesn’t seem to make any difference if I select Agent environment to be Windows native or Windows Subsystem for Linux in the app General settings as they both lag the same way. The same issue occurs with VS Code extension using remote connection to WSL. Codex CLI inside WSL has no such problems. Is there something I’m missing/using wrong?

A little advice here, try some cache clearing. Cache could slow your computer too.
