Discussion on: Why you should NOT use Material-UI

I had a similar problem with Box etc, mostly based on the fact that the way MUI uses JSS causes vast numbers of things to be added as styles, constantly... In fact in my app "insertBefore" for a style was taking 60% of the rendering time, and goodness knows how much the rest was doing. I found a reasonably easy fix by replacing box with my own version and changing makeStyles from MUI to my own version that caches better. Performance is massively improved.
