I guess you could simply rate-limit your login/signup if your not worried about a DoS and just want to keep people from brute-forcing a password.

On the other hand, it's not simply "a performance optimization" as there is no way for node to handle a DDoS without crazy amounts of hardware relative to what iptables|nginx can handle.

You're the one talking about DoS.

Notice how "rate-limiting" is a much more generic concept.

For example, Hacker News rate-limits the amount of posts you can make in a window of time. That's not because they think you're trying to DoS them.
