This is just the beginning. Finally we can do the kind of web performance improvements we couldn't do on the old platform. But to boot, we gained 10-20% on the First Render metrics. And because of the whole new way we deploy, we went from a 27% hit ratio (of popular pages) to 96% in the CDN. That means ~70% of the time you gain about 300-500ms on the initial load. And besides, before, cold cache misses in the CDN would result in a backend server rendering whereas now a cold cache miss just means an S3 lookup.
