VSCode + Codex runs extremly slow? Solution!

Codex
1

Today I went into a strange thing.. I have purged all docker containers from cache and deleted unused volumes because my harddrive only had like 20GB free… After that it only had ~25GB free.. normally I don’t do that regulary, did it last week and it freed ~150 GB.

So I thought I should investigate into that and found out that codex sessions took up ~400GB of space. The last session that I was working in was nearly 200GB after roughly 6 weeks.

VSCode became quiet unusable - and I think that was the reason. I mean when a system has to work in a 200GB file obviously that causes alot of stress to your computer.

So I have told codex to write an ONBOARDING.md .. added a little to make sure another session could find it’s way into the project faster and then I archived all sessions and moved them to another drive.

Then I started a new session and … well blazing fast :slight_smile:

Enjoy!

If I would have to guess having huge session files might also be the reason why sometimes after restarting vscode the harness has some troubles loading the last session.. Huge files cause trouble!

Maybe the codex team can hmm split them up with an index or something once they hit certain sizes?

ahh .. ChatGPT says you are already working on that.. with a DB index and pagination. Never mind! Sounds good!

Another thing to know: I had approx 8000 session files… Which is also problematic when the app has to scan them.. but well, you already know that.
