I don't think this is accurate.  I'm looking at the windows resource monitor while i do tests elsewhere (speedtest.net, the one from my isp, shaperprobe) and they will get up to 70 Mbps in the resource monitor.  I'm not even talking about the final number im talking about what windows is saying the traffic coming to/going from my computer is.  I can use shaperprobe and it connects to a server somewhere around Miami which isnt close to me and see it get a constant 70mpbs on the windows resource monitor.
 
The speed test here says im getting 22 Mbps down, which just isnt true, ive downloaded stuff at a higher rate than that. im supposed to be getting 105 down.  Im trying to troubleshoot an issue with my upload.  This site says I have between 2-5mpbs upload.  I should be getting 20. Again I think the results are on the low side. I think there is some sort of issue with my upload but its not 2mbps regularly. I stream content at 2.5mpbs all the time.  I'm not saying that speedtest.net and my isps test are accurate, im just questioning the accuracy of this one when its obviously inaccurate in my case. 
 
I got the same results trying the multithreading test so its not that.  I just dont get why I can run other tools while monitoring the network bandwidth and they go much much higher, and they arent just on my isp's network.

Thanks for the reply.  I thought shaperprobe was linear, but i actually couldnt tell as it didnt show any data being transferred under the TCP connections in resource manager.
 
I actually did read all that stuff, and im a programmer, just not super familiar with networking.  Im just trying to figure out why all of a sudden within the last 2 weeks I can barely stream.  Comcast keeps saying everything is ok, ive tried 3 different modems, router or no router, wireless and wired, different computers and i cant figure anything out.  Sometimes everything is good, sometimes i dc every 30 seconds. I thought for sure it was a wireless issue, but when i dragged out all the cat5 cables and put them all around my house and hooked up my gaming pc nothing changed. i was able to stream on wireless without a problem for months, with half the upload speed that i have now.
 
Anyways, I changed the server to the alt cdn one and now im getting results that I can believe to be reasonably accurate.  Like 60mps down out of 100.  I can believe that since I think there is a problem with my connection (i know there is a problem with my connection actually just not what) and the linear makes it slower. Plus i pointed speedtest.net to like other servers in dallas and got numbers not too differing.  That I really dont understand.  Why would my numbers drop off so much going from a server right by me to a server in dallas?  Bandwidth isnt a function of distance afaik.... What does that indicate?
 
It was just kinda shocking at first to be like running tests and see literally 10mpbs here and 120 on speedtest.net (connected directly to modem, router is only 100mpbs).  That was with my old computer though. So I apologize for that.
 
I just want to know wtf is wrong with my connection so I can tell my ISP, because they just tell me everything is fine.  It shouldnt be MTU or whatever because everything was working with all the same stuff in my house and then just stopped working fine out of the blue, but i downloaded TCPoptimizer or whatever it is and ran that.

So it seems like at my absolute max that ive gotten here I get about 60% up/down of what im supposed to be getting, and what my isps tool would report.  What can cause that?  Im at my wits end here its going on like 3 weeks of me trying to troubleshoot this. thanks.
