In eCommerce, speed is your most important metric. Mere milliseconds can mean the difference between a sale and an abandoned cart, which could mean millions of dollars in lost sales. I’ve spent a good portion of the last three years in pursuit of page speed, exploring caching, virtual machines, hosting platforms, SSL negotiation time, CSS preprocessing, minification, inline styles and WooCommerce optimizations with the goal of sub-one second pageloads. Using real-world examples, I’ll show you the results I’ve been able to achieve and how to replicate them yourself.
