Too often, any talk of web performance quickly ventures into the land of heavy geekery. Terms like DNS lookups, Gzipping, minifying, far future expires headers, caching, ETags and more are thrown around and consequently lose the attention of most non-techy people. This perpetuates a mentality that performance is solely a technical concern that only developers need to concern themselves with.
It’s time for us to treat performance as an essential design feature, not just as a technical best practice.
