I was mystified by something I was seeing on test results. Loading a web page with a bunch of images was taking up to a minute for the test to complete. That didn’t match my own testing from home, where loading without cache only takes a couple of seconds. I tried all kinds of things to make it faster - HTTP/2, switching Apache to the Event MPM, etc.
Then I noticed in the Advanced Settings section that it was defaulting to a “Cable 5/1 Mb” connection. For somebody with that very slow connection, the test results would actually be about right. Mystery solved. If I change it to “native” then test results match what I am seeing – last run took 1.8 seconds…
My suggestion is that the Connection/Bandwidth setting be moved out of Advanced Settings so it’s always visible, that the list should be updated regularly to match what’s typically available, and that the default choice should be a faster connection than 5/1 Mbps. Connections with gigabit bandwidth (sometimes in both directions!) are available to many people. I personally have a cable connection that gets over 460Mbps down and a reliable 12 Mbps up, and I could pay to get that upgraded.
