Remember that the VAST majority of people using the MS stack will never have any performance problems. Most websites see very little traffic. It's not in MS interest to spend too much time optimising for these niche cases. That's time NOT spent adding features to attract more paying customers. It's better to optimise for revenue. I'm not saying MS doesn't care about performance, of course they do. I'm also not saying the stack is poor. You just have to see it though the lens of their business model.
