A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Hardware Past As Performance Prologue. Regardless, the overall story for hardware progress remains grim, particularly when we recall how long device replacement cycles are: Tap for a larger version.

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. It is physically limited by the speed of light or, practically, how fast signals can travel in wires or in the open air. also “only” take two round trips ((b) is rarely shown).

JavaScript is the single most expensive part of any page in ways that are a function of both network capacity and device speed. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us.
