Well, having a good network card and frequently downloading large files (which I'm guessing lots of people do here, especially those in ML/AI and related fields), I'm not sure why the downloads wouldn't go faster if you didn't have more bandwidth... People use the internet for more than just watching movies you know.

Yeah, for sure, I'm often syncing multi gigabyte repositories while me and my wife are on video conferences. You really feel the extra bandwidth then.

Earlier quoted context omitted.

I've found Fast.com gamed sometimes when traveling in Asia/Europe, in the sense the ISP prioritizes Netflix traffic but normal traffic never gets within 20% of that Fast.com download speed or has much higher latency or something...? With Cloudflare I'm guessing it's a more balanced measure.

> I've found Fast.com gamed sometimes … the ISP prioritizes Netflix traffic The other side of this is why Netflix created Fast.com in the first place: ISPs throttling Netflix traffic (or just having poor peering arrangements that affected it) and blaming Netflix when customers complained about poor video quality (due to Netflix downgrading when experiencing congestion) because some speedtest (that likely the ISP prio…

And they’ve figured out how to get around that. T-Mobile will show full speed on fast but if you have SD video enabled it’ll throttle Netflix videos but not fast.

Haven’t downloaded any 150+ GB games (or patches even these days) off of Steam lately I see

Nice. Every speed test should have a "latency under load" graph, because we can't fight bufferbloat if we can't see it.

DSLReports had the first bufferbloat test I'm aware of, but it's broken now. Another example is https://www.waveform.com/tools/bufferbloat

Ideally this problem should be fixed by ISPs and modem manufacturers, but individuals can use OpenWrt with luci-app-sqm, at least when the connection has a predictable speed limit.

An option to choose between IPv4/IPv6 (or test both) would probably be useful.

Ah the Waveform test is ours! I've been meaning to post it properly to HN since we launched it.

It's far from being a perfect bufferbloat/latency under load test, and there's lots of room to improve it, but we built it when DSL Reports seemed to be running a little unreliably.

We actually use Cloudflare and Fastly on the backend for latency/speed testing. We built and host the test for free mostly because I wanted it, but I justified the dev time as it being very-roundabout marketing for us - so if you ever need a signal booster or MIMO antenna for 5G internet, looks us up :).
