I think you misinterpreted me a bit. I don't believe CF's benchmark was designed to be misleading or biased. I think the benchmark had a perfectly reasonable setup and was actually representative of one relevant use case -- the case of an app that just returns a response without a lot of processing. I think Fastly's criticisms of the benchmark are surprisingly weak compared to the strong language they are couched in, and the strong language itself is what I refer to as "mud-slinging".

My point about benchmarks in general was that unless your application is extremely similar to the one tested -- which is unlikely -- then these numbers don't really tell you much about how your own app will perform. This is a criticism I have of every benchmark that attempts to compare performance between very different technologies. I don't think it makes such benchmarks unethical, just not very useful.
