We’ve also been tightening Codex performance across the app, especially for large repos and active coding sessions.

• ~75% less re-rendering when switching threads

• Some streaming paths dropped to 0 unnecessary re-renders

• Expensive Git operations in large repos reduced by ~10-50x, depending on the operation

• Less UI churn across streaming responses, thread switching, and sidebar interactions

• Faster time to usefulness around startup and first interaction

Less background churn. More responsive coding.
