Not that unique, as in snowflake-unique. There are several classes of deployments, that's all. A lot of things are similar.

That said, benchmarks still say a lot, when the performance gets over some limit. A 10-50% speed improvement could be alleviated with a different config. Even a 100%. I doubt a 10x one could. Or 1/5 the memory usage. Or getting to 20,000 rps on the same otherwise setup, while the other server stuggles after 4000 reqs.
