About the project

We tested Next.js 12.2 Edge Server-Rendering to see the performance gains with using Sanity. We took initial inspiration from the fireship video here, but specifically we were curious to see if we would see similar results with Sanity. What we found was pretty impressive. From a cold start, we found the node.js SSR could take up to 1.5 seconds, whereas we were getting fairly consistent sub 0.7 seconds on the new edge SSR
