are there any researched measurements to show exactly how much is available? obviously it would vary greatly depending on where the connection is going... but wondering if there is some overarching idea of what it has..

https://metrics.torproject.org/bandwidth.html https://metrics.torproject.org/bandwidth.html Currently the network is processing ~125Gbit/s of traffic.

  is there a way to see the average bandwidth a tor end user would get? seems like a good amount?

    I assume you mean exit traffic. Exit traffic is anything connecting to the open internet, whereas hidden services never leaves the Tor network. For exit traffic I don't believe there is a metric for average user speed. But, I just ran a 3 speed tests using different circuits and was getting 500-800KB/s download speeds on average.

Try using it. Very slow. No matter where you are. I understand that some people have no choice other than to use it. so I stopped using it to leave whatever bandwidth there is in the exit nodes to them

  I use it to control my 3d printers at our local hackerspace. I have octoprint set up with a IP behind a NAT, and a hidden service. When I'm not at the 'space, I use Orbot on my android and OctoRemote. I get reasonably good speeds and latency. I can also view my webcam on the printer. It's not 4HD by any means, but is definitely usable.

    It wouldn't be surprising if hidden services had a lot better performance. Running a guard node is a lot less risky than an exit, so there's probably a lot more capacity available for traffic staying inside the network.

      That makes a lot more sense, regarding in-Tor bandwidth. I've also had quite a few projects in which I'm trying to normalize Tor usage. My biggest one thus to date is a Tor-ified IoT network that uses your own resources instead of nebulous "cloud" providers. https://hackaday.io/project/12985-multisite-homeofficehackerspace-automation https://hackaday.io/project/12985-multisite-homeofficehacker... Long story short, there's a lot of promise to a .onion address, given it acts like a telephone number. Change IPs? Who cares. You retain your "number" no matter where you move :) It's also a lot less scary when talking to people about this, and how Tor is awesome in many areas.

        Yes, Tor hidden services are neat technology, using them for IoT is a clever idea. Authenticated, not really scannable and you avoid the typical issue of going out to someone pre-determined to get connectivity from the outside.

        This only works for HSv3 though. HSv2 addresses are enumerable without too too much work.

      They perform quite worse: https://metrics.torproject.org/torperf.html?start=2018-05-15&end=2018-08-13&source=all&server=public&filesize=5mb https://metrics.torproject.org/torperf.html?start=2018-05-15... https://metrics.torproject.org/torperf.html?start=2018-05-15&end=2018-08-13&source=all&server=onion&filesize=5mb https://metrics.torproject.org/torperf.html?start=2018-05-15... You can see that for a 5MiB file, hidden services perform 2-3 times slower, I would put most of the blame on data having to travel through more hops when using hidden services.

You can see that for a 5MiB file average download time is around 12 seconds [0], which is around 425KiB/s, the main problem with Tor is latency, downloading a 50KiB file takes around 1 to 2 seconds.
