Afaict, HN is still running on a rusty potato. The software's written well, so it doesn't need to run on more than that. (What's going to happen to it? Someone links to it from HN?)
> one of the more important and trafficked properties on the Internet.
I like HN, but it's really only important within a very niche subset of the Internet, and it also doesn't have much traffic. There's like a single post submitted every two minutes. That's not much.
I think [being unable to handle peak load] does not imply efficiency. Unless perhaps this is a joke that I’m misunderstanding?
Nonetheless, i suspect that HN probably is quite efficient, just based on what I know about dang. Even so, the parent claim was that it was popular and important, not that it was efficient
