I know, but is there any proof of this? And how can we be sure that the .NET environment is better optimised than the PHP environment? I would find it weird for them to shoot themselves in the foot like that. Since if someone were to make a decent blog post that showed proof they'd only have C# programs on Azure...
This all being said they're pretty transparent with their benchmarks. They supply all the code that they've used and are even comparing it to another project which aims to do the same.
I guess I'm just a bit angry because people are just saying "It's unfair" while they can easily do the tests themselves and then call someone out for it.
