First Byte Time “FBT” findings and research results

RE: First Byte Time “FBT” findings and research results
FWIW, routing dynamic traffic through a CDN can also make sense as long as the CDN is good at it. Akamai calls it DSA but most hagve offerings in that space.

It can reduce the connection set-up time between the users and the edge but that only works well if they maintain long-lived connections back to the origin or otherwise route the requests through their network and egress close to the origin. It can also help with slow start in that configuration.

Some of the CDN's will do more dynamic edge-serving with something like Edge-Side Includes (ESI) or flush a static initial part of the page to get the browser started while the origin does the heavy work for generating the full page.

Where it REALLY pays off is in the move to HTTP/2. Serving the static assets over the already-established connection for the base page can be a huge win.
