> To do that the team needs experience with performance, and most of internet programmer culture is just to lecture people about how programmers are cheaper than hardware if anyone asks or talks about performance. But this is an absolute truth, isn't it? I mean, what's more important to your business: avoid the need to launch an EC2 instance, or implement that user flow in one day instead of one week? Do you care if it takes 50ms to show your dialog box instead of 40ms? Do you really care if you pass all your objects by value, with a few deep copies, instead of passing everything by reference? The truth of the matter is that in general all performance bottlenecks are caused by software architecture and algorithms, not "clean code" implementations.
