I'm beating a dead horse here, but benchmarks aren't a useful way to compare UI frameworks, because:

1. The benchmarks aren't always going to be fair - e.g., in this article they talk about rendering 3,000 rows, but that's an unrealistic benchmark (you'd want to use list virtualization in any framework at that point) that is obviously more favorable to some frameworks over others.

2. Most frameworks are fast enough for most tasks. The performance of a framework is rarely the main issue, but benchmark scores are quantitative and sound objective, so people cling to them.
