Sometimes when benchmarks are posted on HN that compares your own product (A) with a competitor's product (B), someone working for the competitor refutes the claims made in the blog and states that B were not given the same requirements as A. This particular thread comes to mind [1]. Maybe this is due to the blog writers misunderstanding B or maybe the competitor misunderstands A, or maybe there is a better way to do what was benchmarked using B. I think a better way would be to use some standard benchmark, and publish the code used for benchmarking them.
