As a culture, we are are obsessive about 'performance'. My purely anecdotal impression is quite the opposite. Speed of delivery and convenience for the developer (not the end user) seem to be the norm. Frameworks, scripting languages, browser-based desktop and web apps: none of these have the characteristics of being small, nimble, lightweight, or performant. They certainly make life easier for the developer. Whether users get a 'good experience' out of the end result is open to debate.
