A CDN is a network of globally distributed servers that cache and deliver content such as images, videos and static files to end users, thus reducing latency and improving page load times.
Now that we know what a CDN is, can you imagine the caching mess we'd have with two CDNs working simultaneously? It's like having two DJs playing at the same time, only one sends a song and the other plays another one on top of it, complicated right? This would result in unpredictable behavior and possibly outdated or incorrect content being delivered to users, plus traffic would have to pass through yet another entry and exit point, and this could increase latency and potentially decrease your site's performance rather than improve it, and that's not what we want, right?
Therefore, we suggest that you only use Peqi, because not only can you control the optimization without adjusting anything in your application, but it will work as a CDN that will improve your site's performance even more.
