After giving a talk at WordCamp Ubud 2017 — where I showed how to use a $5 Vultr box and Redis with Load Impact to support up to 7000 concurrent WordPress users — I was asked to help turn some of the performance optimization work demoed into a WordPress plug-in. This is that plugin, currently in beta:
It’s the first of it’s kind — and like no other performance plugin to precede it. Based on initial tests it speeds up the stock Twenty Seventeen theme about 300% and I suspect time will show even greater gains for other themes. It builds on top of a performance optimization technique called Fetch Injection, enabling external scripts to download asynchronously in parallel while preserving execution order.
