In that example, I bet WordPress on its own would have spent less than 550ms without having to replenish your cache layer. Also how much of that time was actually PHP vs. PHP waiting for MySQL? I bet if you scattered microtimers throughout WordPress, you would see 99% of your 550ms would be waiting for the disk and MySQL.

No, actually MySQL was the remainder (~150ms).
WordPress wasn't updating the cache; I mention that because 700ms is painfully slow, once all the JS and ads run load time can cross 2 full seconds. The cache becomes the only acceptable way to run it in production.
New Relic actually provides a breakdown of how much time was spent in each function; while I don't remember offhand what that was, there wasn't any low-hanging fruit that could be optimized.
