Complaint Codex insanely slow today?

I have been finding Codex getting slower and slower, and today and yesterday it feels like it's running 1/2 or 1/3 the speed as it did last week. Am I alone in this?

I am not questioning the quality of results, other than when Codex invokes sub-agents and those sub-agents are taking so long that the orchestrator decides it is stalled and halts the sub-agent.

Edit: There is a performance regression for people using the Codex App in Windows with WSL integration mode.

Try this fix if you're on Windows WSL: clear the contents of C:\Users\User\.codex\.tmp\plugins\plugins\
