Wow I didn’t know this I thought I was paying fuck all for my internet and it was performing terrible. 

So if I have 1.5 gig speed and I’m getting 100MB/s is performing as it should be?

Yup! Tho it gets ever so slightly more in-depth:

1.5 Gbps is 1536 Mbps (technically the correct factor is 1024, not 1000) which is equal to a theoretical max of 192 MBps (i didn’t explicitly say it earlier but you’re supposed to use lower case b for bits (the smaller quantity), and Upper case B for Bytes (1 B = 8 b))

at 100 you’re only getting a bit over half that but there’s more to the story.

Your network speed is always limited to the slowest link in the chain (steam/speed test servers-&gt;their local network speed-&gt;their internet speed-&gt;a whoooole bunch of data center’s individual internal and internet speeds-&gt;your internet speed-&gt; your local network speed).
You can usually assume that only your internet and local network speed is the slowest of all those, since big companies and data centers have usually multiple, 25+Gbps internet speeds and even faster local speeds. 

So if you’re paying for 1.5 Gbps and your using slow wifi, you’re not gonna get anywhere near 1.5Gbps. if you use a wired ethernet connection to your router, you’re likely using 1 Gbps ethernet and are not gonna get above the theoretical max of 128 MBps (realistically up to about 100-110 MBps. 

You’re paying for 1.5 so that you can use mutiple wired connections and/or wifi at the same time where for example your downloading at 1Gbps to your pc from steam, and your roommate’s/family member’s Netflix for example isn’t gonna slow you down at all.

if your router has a 2.5Gbps ethernet port (or above) and your pc does too and you’re using a half decent cable you should be able to get close to the 1.5 Gbps max speed to your pc if everything’s set up right.

Hope this helps to explain the whole situation if you have any further questions i know a bunch of networking stuff (tho definitely not all) :]
