You should take any results anywhere with a pinch of salt. However, it's not that benchmarks are meaningless -- review their methods. If you can think of a way to test that they're not following, or find some flaw in their testing methodology, then tell them about it, and have them fix it (or post what's wrong somewhere), but they are pretty up front about HOW they test, so results should not surprise you, given enough knowledge of the frameworks involved (if they test something that flask is great at and tornado is not, that will be obvious given knowledge of how the test was conducted)
