The CDN does not have nodes in Eastern Asia or Africa, so one experiment would be to try a different CDN for a portion of the traffic and watch for a positive impact on the page-load times from real users. Perhaps it is latency we should be optimizing for when deciding on an ISP, and not just bandwidth? So, how fast is your website? The W3C Web Performance Group recognized the clock issue, as well as the need for granularity beyond one-millisecond resolution, and also introduced the High Resolution Time specification. The success of your performance and optimization strategy is directly correlated to your ability to define and iterate on application-specific benchmarks and criteria.
