Anyone tried using Fast.com?

I have just seen this thread and I thought that I would say that one of my favourite speed testers is the following:


However, I don't know for certain how accurate it is.
You mean like the same speed tester that Mark links to on this very website?


I thinks it’s pretty well respected and reasonably accurate. 😎
 
Cloudflare one always gave me the worst results, which may well be true, but I guess my subconscious mind ruled it out. 😅
lol, Cloudflare's speed test gives me about 1 Mbps.

This is nonsense. I'm on a 4G/5G connection. Although the speed can can drop to 20 Mbps, I think it easily averages 50+ Mbps, and can peak to 80 Mbps, or even 100 Mbps.

It looks like Cloudflare's checker tries only a 100 kB download. In contrast, for upload it tries 100 kB, 1 MB, and 10 MB. I think the variable/high latency throws it off.

You need to leave it running for some time. It does use chunks. You'll see it tests various things, then comes back to the speed test and should increase in speed.

But yeah 1Mbps seems kinda ridiculous.

I think it best not to rely on any one speedtest service, check multiple ones. At the end of the day, they're all servers you connect to and are thus subject to different levels of throughput due to utilisation, network bandwidth available, path taken to traverse the internet etc although I'd be surprised if there were any issues with cloudflare, given they've got several hundred terabits of bandwidth to play with (they offer a DDoS scrubbing service and have tons of bandwidth available).
