CloudFlare one is giving me less than 1/3 the download speed fast.com shows, and in fact, testing by downloading a Linux ISO [1], the latter seems to be the correct one. I don't know what CloudFlare's test is doing (their server is geographically nearby) but I obviously can't trust their measurement.

That's probably due to your ISP imo, they're known to favor some routes/servers Or the cabling to the cloudfare server is worse than to other servers

  My ISP is unlikely to be a problem. I literally get higher speeds downloading from servers across the world in Australia [1] than from CloudFlare's benchmark. Something around CF's side is funny, not mine. I'm looking at the network tab, it seems like they send a ton of small requests instead of a large one... which might point in the direction of the problem.

    The issue is likely not with Cloudflare, but with the connection between your ISP and Cloudflare. That's why this speed test is relevant - if your ISP can't manage to make good, settlement free* connections (=peering) to Cf it's not a good ISP. Example: Rackspace Sydney (AS58683) has (likely paid) peering with AS7474, who has peering with German Deutsche Telekom (AS3320). Peering with DT is significantly more expensive than many others because they have a regional monopoly. * Cloudflare is present at many regional Internet Exchanges and any good ISP connects to these, too. Some don't, however, like Deutsche Telekom.

      When CloudFlare is the odd one out having trouble with people's ISPs (just read other people's comments right here about their experiences with that benchmark... I'm not exactly the only one getting weird results) and when my ISP isn't having the same trouble when connecting to other servers across the world, blaming my ISP is... weird. It's a little bit like driving on the other side of the highway and then blaming everyone else for driving the wrong way. But I mean, if you still prefer to blame everyone but CF, by all means feel free.
