The document discusses the importance of performance in software architecture from the perspectives of both developers and architects. It notes that performance is a non-functional requirement that is difficult for developers and architects to align on due to different ways of thinking - developers focus on the code itself while architects have a higher-level view of systems and interactions. The document advocates that architects must look beyond guidelines to further communicate performance requirements and priorities to developers in order to iteratively improve agility and performance.
