X10 latency in US comparing to Europe

Hi.
I have some domain proxied by CF and have some caching enabled. The sample resource is https://assets.experify.io/test/baloons.jpg

When I am requesting this resource from my location (europe) it is super fast and cached entry is returned in 50-70ms (cf-cache-status: HIT), but I am getting complains from customers in US that our page speed is slow, and indeed, after testing on US VPN this resource is slow (like 500-600ms in total).

  1. I think testing the speed via US VPN while I am physically in Europe does not make sense, right?
  2. Is there someone hosted in US that can try to check what is the response time of this sample resource in US? (important to have cf-cache-status: HIT, just to measure only CF latency, not origin)

Right, because you have the added latency to your VPN server.

The meerkats seems to be pretty convinced it works fine in Chicago - sitemeer.com/#https://assets.experify.io/test/baloons.jpg
