I think an equally interesting result would be to keep only the worst 1-4 benchmark results and compare those. In my experience some frameworks put much more long-term memory pressure on the GC, and by discarding those, your benchmark turns a blind eye on that.

In another words, I'd be interested more on the worst possible performance of a given framework, than their best (assuming the app is written in a reasonably good way otherwise).

Also, +1 to the sibling post that asks for longer runs, that would solve the GC question by including it altogether!
