Argo Analytics does not display performance data.
I run Argo for few weeks now. Unfortunately I have never seen any performance data.
All traffic goes through public host names.
I always have this message:
Argo Smart Routing is optimizing XX% of requests to your origin.
Where XX is in the range 50 – 100.
I think that something goes wrong with my Ago Smart Routing.
I use it as well, however despite I am not quite sure which kind of “performance data” you’d want and like to see?; I can admit I do see significant improvement when loading my Website with Argo Smart Routing enabled, especially for the specific colocations from where my end-visitors are mostly coming to my Website.
Do your refer to the message such as below example? 
Argo Smart Routing is optimizing 49.0% of requests to your origin. There have not been enough requests to your origin in the last 48 hours to display detailed performance data.
That’s what I see on one of my zones where I do see improvement a lot, since it’s Joomla CMS. Direct link → https://dash.cloudflare.com/?to=/:account/:zone/traffic.
On the other zone, I can see the graph since I’ve got quite a lot of daily visitors and traffic there. It’s more percentage % of improvement for the farthest end-visitors.
Example:
Possibly I can make a guess from where the traffic comes.
But it is not clear to me about the improvement.
I have created a new domain name, put this domain on CF, moved all services from the old domain name to the new one. The traffic runs for more than 4 days already. The services are on the same physical server.
Unfortunately Argo Analytics always shows the same message:
“Argo Smart Routing is optimizing 0.0% of requests to your origin….”
My old domain continues to show me “Argo Smart Routing is optimizing 73.4% of requests to your origin. There have not been enough requests to your origin in the last 48 hours to display detailed performance data.” Still there is no performance data.
The picture below corresponds to the new domain name. Argo Analytics: “Argo Smart Routing is optimizing 0.0% of requests to your origin….”
I’m experiencing the same issue.
Did you solve the problem?
I have noticed that if people come from Russia (I have a different zone for them) then CF does not optimize the traffic. I do not know how traffic goes from their data center in Moscow (DME) to the data center in Frankfurt (FRA) where my server is connected through the tunnel. As a possible guess I would suggest that it goes via WAW and ARN. To see that you can look at DNS analytics. If people come from Europe then CF is able to optimize the traffic up to 60% (“Argo Smart Routing is optimizing 62.7% of requests to your origin.”)
Regardless the volume of the traffic and the number of request you will always have 0% for users coming from some countries.
To determine the data center users use you could ask them to look at https://your.domain.name/cdn-cgi/trace
So my guess is that for some remote countries CF relies on the internet exchange points (xxx-IX) => “Argo Smart Routing is optimizing 0.0% of requests to your origin”
We should wait for an expert to clarify what are other benefits of Argo Smart Routing, if any, for locations where CF is unable to optimize the traffic. It’s an open question.
Is there any sens to activate Smart Routing on such zones? Probably not.
But I heard people who have configured a tunnel for a live streaming have complained that their tunnel had stopped suddenly to work after some time. They suggested that there is some bandwidth limit for free plans.
