I'm curious about the real-world impact of using a Content Delivery Network (CDN). I understand that CDNs use multiple servers worldwide to deliver content closer to users, thus reducing latency and improving speed. However, I'm wondering how significant this difference really is when compared to serving files from a single server located in one region. I set up a test with a simple frontend app deployed across various locations, including Frankfurt, London, Toronto, and Sydney. I ran load tests to compare response times based purely on distance. Can anyone share insights on whether it's worth implementing a CDN for your specific needs, especially if your audience is primarily local?

Congrats on setting up your own test! The impact of a CDN really varies by context. If your content isn't seeing massive traffic, then the difference might not be that noticeable. But if you're getting millions of views, even optimizing delivery through a CDN can be worth it to enhance user experience—especially for global audiences.
Absolutely! If you’re serving users worldwide, a CDN can offer huge benefits. We've seen latency drop from 300 milliseconds to just 30 milliseconds for users in the US accessing files from our European servers—definitely worth considering if you have a diverse audience!
I think you missed a key takeaway in your results. Your tests were focused on latency between different server locations, and that’s a good start to gauge performance. However, it’d be neat to see how these results stack up against actual CDN services. For heavily loaded sites or international users, a CDN can significantly improve loading times.
