Re: Speed Test
#62Why do these speed tests start out slow and then get faster over the course of a few seconds? Is it something about the internet that means the speed changes so much over the course of the test?
That's how TCP works. TCP initially starts with a small transmission buffer (the congestion window), and gradually increases its size until it starts getting errors (packet drops or reordering).

There is a csv export and sharing to twitter and facebook for me, right nect to pause/retest
Re: Speed Test
#64Smart. With a bit of SEO/marketing, this will become the way consumers judge their internet quality. If connection quality = ping to cloudflare then that puts cloudflare in a very strong negotiating position for peering agreements etc.

Not how it’s usually measured…link speed is pretty much always in bits/s
I don't measure file size in bits. I don't want to multiply/divide by 8 when roughly estimating how long a download will take. I end up doing 10 instead for maximum ease and pessimism.
Link speed has always been measured in bits/s or as sibling comment suggests baud which is, still, just bits per second.
Obviously a huge part of this is marketing for modems, ISPs, network cards, etc. but it’s consistent. The conversion to GB/s is fairly simple and doable with the super key, or super space on Mac in every modern OS…
I agree with you that the difference is irritating, but wouldn’t have done any different if I were Cloudflare.

There are decent alternatives for this. Fast.com is hosted by Netflix, making them an excellent speedtest to check for service throttling. Google has a speedtest as well (Google "speed test" and it'll show a button).
The more of these tests start appearing, the better.

#67No way to use bytes instead of bits in the output?

But it's not measuring link speed directly. It's measuring transfer rate through TCP which is byte oriented. It's not possible to receive partial bytes via TCP (or UDP for that matter).

Indeed, that's part of what motivated netflix to make fast.com.
is it possible for ISP to distinguish Netflix video streams from connections to Fast.com ? (and throttle them differently) PS: my latest ISP router doesn't let me change DNS to my local pi-hole. haven't explored all options yet - just got new one 2 days ago -- but currently my DNS queries are going to whatever is the default set by my ISP.
I've never used a pi-hole; but assuming it works as a DHCP server and a DNS resolver, then you should only need to disable DHCP in your router. I've never seen a router than wouldn't let you disable the DHCP server.

Google partners with Measurement Lab (M-Lab) to run this test.

> baud which is, still, just bits per second.
Isn't the baud-rate the number of signal transitions per second? How that maps to bits per second depends on the wire encoding.
