Testing performance from rails/rails#35629

This only compares this PR vs its parent. (ie. "before" already includes #35623)

I stacked the deck a little to make this change look as good as possible:

• Rendered quite a few different templates
• Used a very fast test app
• Commented out js/css tags in header (the slowest part of the page in dev)

But the results were very good:
