I think what they are trying to say is that try everything yourself and see and don't just blindly believe in benchmarks.

And also mentioned on the same page is this :

In the spirit of demonstrating typical performance characteristics, the benchmarks presented in this comparison page are implemented in an apples-to-apples, naive, idiomatic way (i.e. the way you would normally write 99% of your code) and do not employ tricks or advanced optimizations to make one or other framework look artificially better. You are encouraged to contribute a PR if you feel any DbMonster implementation here could be written more idiomatically.
