I am getting around 23-125 download speed over WiFi with my MacBook Pro and upload speeds around 768. I have AT&T fiber with a 1 Gig connection. My wife's MacBook gets about 850 both upload and download. My iPhone and iPad both get around 650 upload and download. What is choking the speed on my MacBook Pro?
MacBook Pro 15″, macOS 10.13
Poisoning Internet performance:
By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself. The main reason is that they are relentless in scanning your files, non-stop, looking for things virus-like patterns in Everything. When completed, they do it all again.
The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.
You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.
Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, but are not inherently dangerous.

now that we have the obvious performance poisoners out of the way...
Hold down the Option key while you click on the Wi-Fi Icon on the Menubar. you get snapshot of current performance parameters, like the older one below. Screenshot, photograph, or transcribe the values and post in a reply
All three party software has been removed long ago and the issue extends to AppleTV devices when I run the speed test on them? Since there are no third party filters on Apple TV....What is the answer to that?
Slow download speeds and fast upload speeds
