David Kimura PRO said over 5 years ago on ViewComponent in Rails :
```In early benchmarks, we’ve seen performance improvements over the existing rendering pipeline. For a test page with nested renders 10 levels deep, we’re seeing around a 5x increase in speed over partials: Comparison: component: 6515.4 i/s partial: 1251.2 i/s - 5.21x slower ``` It is interesting, they're showing 5x difference in some cases. Perhaps one level deep, the difference would be small, but on 10 levels deep, that's a pretty significant change.
