About This Demo
A transparent look at how this demo was built, what it simulates, and where the numbers come from.
What this demo simulates
This is a controlled static simulation, not a live URL loader. The browser frame contains a purpose-built mockup page designed to illustrate the performance gap between unoptimized origin delivery and edge-accelerated delivery. Real URL loading was considered and rejected: most production websites block iframe embedding via security headers, which would cause silent failures at exactly the wrong moment. A clearly-labeled simulation is more honest and more reliable.
The OFF state simulates a page served from a single origin server with no CDN, no image optimization, no caching strategy, and uncompressed assets. The loading times and metric values are loosely based on real-world benchmarks for unoptimized pages served from a single US-East origin to a European user.
Where the numbers come from
Metric values in the ON state reflect documented performance improvements from bunny.net's CDN, Optimizer, and caching features. Image compression ratios are based on WebP conversion benchmarks (average 85–93% reduction from uncompressed JPEG). Latency improvements reflect the difference between a single-origin round trip (~180ms transatlantic) versus edge delivery (~18ms from nearest PoP).
What this is not
This is not a real performance test of any website. It is a demonstrative simulation designed to illustrate the categories of improvement that edge delivery infrastructure provides. For real-world performance testing, see bunny.net's documentation or run a Lighthouse audit.
Built with
Lovable and Claude Code, deployed to bunny.vladstoiculescu.ro. Built as a take-home task submission for the Developer Product Marketer role at bunny.net. Github code available by request.
