How does Tor protect against flooding with artificially long circuits
The type of attack you are describing is a congestion attack. In theory, the simplest form of such an attack would be a general DoS on the Tor network.
Taking things one step further, a congestion ...

What is the most appropriate kind of hardware to run a Tor relay on?
TL;DR:
Tor does not make much use of more than one core, two cores (or one hyperthreaded core) per process is best

Finding available bandwidth of a relay
Not really. You can know it's observed bandwidth, and what it's throughput has been seen to be but not "available" bandwidth. That would require knowledge of, for example, the upperbounds of ...

Fast/Slow relays in Tor
From the directory spec, the threshold is almost always 100 KB/s.
A router is 'Fast' if it is active, and its bandwidth is either in the top 7/8ths for known active routers or at least 100KB/s.

How does TOR divide bandwidth fairly between clients?
Tor doesn't use per-user prioritization because this is very difficult to do in an anonymity network. Instead each relay uses per-circuit prioritization. The main use-case for Tor is interactive web ...
