# Link: Moving Beyond End-to-End Path Information to Optimize CDN Performance

[Moving Beyond End-to-End Path Information to Optimize CDN Performance](http://research.google.com/pubs/pub35590.html)

> Our main result is that redirecting every client to the server with least latency does not suffice to optimize client latencies. First, even though most clients are served by a geographically nearby CDN node, a sizeable fraction of clients experience latencies several tens of milliseconds higher than other clients in the same region. Second, we find that queueing delays often override the benefits of a client interacting with a nearby server.
