The goal of this document is to start a discussion around how we can better communicate and estimate the performance cost of designs according to what is what information is displayed on a pages.
Often the limitations and performance implications of a design only become apparent after the design and even after the design was implemented. Resulting in slow(-er) pages and the need to go back and tweak or fix at least the implementation of the design and sometimes even the design itself.
This is an attempt at making the performance cost of a design more visible and communicable.
