Compression

1 Gbps is computationally 1.24416.

Some testing software in my experience can give you a higher speed than what you are getting and vice/versa.

For example the Xbox internal test in settings can give me a speed of +600mbps whereas a Google test on a wired connection can give me 300mbps on a 550mbps connection

Fast.com tends to give higher numbers. One of reason I personally don’t trust them (for accuracy). When I do iPerf (local test), Xfinity with correct server location seems be more concordant with my result.

However, relatively speaking I think they can still be used, just to absolute number.

Are you using cabling or are you on Wifi? If it is cabling, it is natural that the transfer will be of better speed and stability.

I believe that by announcing 1gb, the manufacturer of a router is guaranteeing an “official” maximum speed that it is capable of traveling, it does not necessarily mean that some extra megabytes can not be transferred.

It’s more reasonable to announce 1gb than to advertise 1.2 and have hoards of clients complaining that they are measuring only 1.1, for example. Anything that exceeds this 1gb “limit” will be perceived as bonus and customer satisfaction with the brand will be higher.

🤫, act cool, nothing to see here Mr internet provider company.

I always recommend doing actual test file downloads.
There’s plenty of sites you can use, download multiple of the larger files, even on different computers to really saturate the network.

Depends on where the server is. Being 1 gig means it is capable of that speed. You have better speed than like 95% of everyone.

Test it with iperf3

On a side note…

You are usually provisioned for the 1.2 Gbps.

If you get you a modem and a router that has a 2.5 Gbps port or higher, as well as your computer having it as well, you will get speed tests close to the 1.2 Gbps as well

Bits, bytes, rounding, bad math, and maybe compression

I tend to get 20% faster than the service I’m paying for as well. I’m not sure why but I’m not mad.
