I added these lines at the end of my torrc file. On Macs this is found at ..Library/Application Support/TorBrowser/Tor
Since I am based in the US, it specifies 10 really fast entry and exit servers, and requires that the middle relay server be based in the US as well. (US is the only country not excluded)
It has sped up Tor 4x or more for me, much more usable now. Maybe a bit less anonymous, as the signal is just bouncing around the country not the entire world... but should be anonymous enough.
You can alter the middle relay country based on your location, and use
https://atlas.torproject.org/ and the ping command in terminal to find entry/exit servers that are fast for you.
