passenger 5 performance compared to unicorn/thin/puma/etc

I've been searching around for performance tests on the new passenger 5 as I read here it became way faster. I tried to find other ressources confirming this but no luck. Has anyone tried to install it and see the difference?

Passenger5にすることでレスポンスは速くはならないが、メモリ消費量が減ったのでHerokuのDynoの数は減らせたという記述が。ベンチマークは最適化された結果なので結構眉唾ものっぽいのかな…。
