You are right. There are many positive things about TechEmpower and keeping it open to all and running takes an incredible amount of effort, which is definitely appreciated and I failed to recognize. That was unfair of me.
Although I still strongly disagree with the initial observation that they are "real world". Most applications in the real world receive heterogeneous traffic, from a varying and unknown number of clients, with logging, potential contention on resources, and other aspects that are not taken into consideration.
