Tài liệu High Performance Website

In eighth grade, my history class studied the efficiency experts of the Industrial Revo-lution.I was enthralled by the techniques they used to identify and overcome bottle-necks in manufacturing.The most elegant improvement, in my mind, was the
adjustable stepstool that afforded workers of different heights the ability to more
easily reach the conveyor belt—a simple investment that resulted in improved perfor-mance for the life of the process.
Three decades later, I enjoy comparing the best practices in this book to that 19th-century stepstool.These best practices enhance an existing process.They require
some upfront investment, but the cost is small—especially in comparison to the
gains.And once these improvements are put in place, they continue to boost perfor-mance over the life of the development process.I hope you’ll find these rules for
building high performance web sites to be elegant improvements that benefit you
and your users
