The numbers shown here are best-run results for all frameworks, except for Mithril's case, for which I'm taking the worst-run result. The numbers aren't statistically rigorous (e.g. I didn't bother to calculate standard deviation), but they should be enough to give a rough idea of what is faster than what.
Generally speaking, these tests are making a deliberate effort to be biased in favor of other frameworks: for example, I don't load "optional-but-usually-used-in-real-life" things like the router module for Angular, or Marionette in Backbone's case, and I load the entirety of Mithril. In addition, this test deliberately avoids triggering requestAnimationFrame-based performance optimizations for Mithril, since this optimization does not exist in many frameworks and severely skews numbers in Mithril's favor in CPU-intensive situations like parallax sites. I'm also NOT using the Mithril template compiler, which would also skew the benchmark in Mithril's favor.
