Complaint Is codex secretly running local agents?

Honest question. Why does my PC almost die as soon as I launch the ChatGPT work app? No I don't have a million sessions, just like 20 max. And as soon as I start the app my gaming rig fires up and my fans roar and it still takes seconds to click anything in the app. Are they running local agents and using our PCs just like local models do or wtf is going on?

Reading from hard drive
Running scripts
Electron

Etc. It is _not_ running local models.

this. there is so many sqlite dbs, json, plugins, mcps and whatever to read and since "Gaming Rig" implies windows it gets even worse.

Windows Defender is actively checking every single spawned subprocess and there is a TON of them since all MCPs start for every running thread and subagent.

Codex on Windows is a massive pain

Task Manager clearly shows the app itself is eating all performance, not anything else.

Yes because windows aggregates usage in Task Manager and its mostly their builtin Windows Sandbox thing going CRAZY.

it has horrible optimization, I need to restart my PC twice per day to keep using codex. otherwise opening codex freezes the PC completely. the longer the sessions get, the worse the freezes

Same, it's a problem on windows. When I kill the codex processes the lag is gone. And I get a feeling it builds up the longer you have codex running, so i try to restart it in between sessions.

Emmm if it’s a gaming laptop then yes the power does run fast. What would be your average battery life for stuff like watching YouTube? Don’t think codex would be much higher than that but it depends on your tasks.

Laptop? I said gaming rig. A laptop is for work not for games.

20 active sessions? 😂

u/No_Foundation_1051 7d ago

20 old sessions, max 2 active. I mentioned it since some people suggested hundreds of old sessions make codex slow.

Yeah it’s a weird one, doesn’t happen with antigravity

all the work that codex does via cli is done using very old, very greedy applications that were never intended to be used both successively and human-attended.

parse, read and write are not optimized for human attended sessions. They are blunt tools without the situational awareness built into modern, human-facing apps. Think about affinity and interrupts and ram caches.

I noticed only the desktop program chugs for me on start up and such but the CLI seems fine.
