Am I being throttled?

Sooo I have purchased internet service recently. I got a 45 Mbps connection (or so I thought), and am currently experiencing problems. The connection is actually really good, but I'm having problems getting the proper speed from the connection i have. The problem comes in when doing actual real world downloading.

This is what a speed test shows up as:

And here is an example of my ACTUAL DL speeds:

My question is simple. Is it possible the ISP is throttling me? or am I expecting too much and my connection is just fine and as it should be. For reference my ISP is AT&T and my area is Dallas, Texas. Thanks in advance any help is greatly appreciated. I've talked to AT&T techs and CSR and they keep trying to explain the difference between a Megabit and a Megabyte to me like I'm an idiot not understanding my actual question. Of course I'm not going to be able download [censored] at 40 MB/s my connection -_-

Are you in the US?

Your second link is useless as it just shows a zip file in a directory (folder) list. If you go to your actual speed test result on thinkbroadband you can give us a direct link, which is just below the result. Assuming you have a login for the main site where the speed tests are, then clicking any result in the list in "My Profile" gives similar.

Like this:- http://www.thinkbroadband.com/speedtest/results.html...

or more neatly like this.

Look at the download speed on the second link it is only at 2.3 MB/s

And if you are in Dallas area, the server you are downloading from is in London UK, and while I'd expect faster many links in between including many out of the control of the provider.

Running the test at http://labs.thinkbroadband.com/speedtest and sharing the results link at the end will be informative, seeing the graph is just as important as the numbers.

Ah - sorry . I didn't realise it was a file download from thinkbroadband you were doing, as opposed to a speed test.

As MrSaffron says, the direct link to the result of the test he suggests could be interesting.

The big difference to a simple file download is that it is a single file request, our speed test does a single request test and then a request for 6 files at once.

This will saturate a connection much more easily, and we do both tests as the difference between the two results can be instructive. Most other testers use something like 8 to 32 downloads at once, so any oddities of the connection are hidden from sight.

2.3MB/s = 19mbps

max speed you should expect is around 5.5MB/s from a us based server

also you're downloading from america don't expect full speed from a uk server as generally your isps like to traffic manage everything.
