-### High frequency updates
-
-The `LinearProgress` uses a transition on the CSS transform property to provide a smooth update between different values.
-The default transition duration is 200ms.
-In the event a parent component updates the `value` prop too quickly, you will at least experience a 200ms delay between the re-render and the progress bar fully updated.
-
-If you need to perform 30 re-renders per second or more, we recommend disabling the transition:
-
-```css
-.MuiLinearProgress-bar {
-  transition: none;
-}
-```
