What is your use case for this server that makes optimizing for LAN vs WAN latency a valuable outcome? I’ve never really noticed that latency in email clients or when using the HN website and so I’m curious what is unique to your specific scenario that makes it a priority.

(This isn’t criticism, but I definitely don’t understand why it’s a criteria in your case yet.)

HN itself is fast, but the comparison I'm making is with readers that use the HN API. See how getting each comment requires an additional API request: https://hacker-news.firebaseio.com/v0/item/22481199.json?pri...

It's more about the consistency of operating on data local to the user. For example, see this comment referencing how HN paginates threads at 250 comments for performance reasons: https://news.ycombinator.com/item?id=22231055 A local database does not have that issue.

Ah, okay, so it's more about having to initiate thousands of requests for a single page than so much about the latency of any single request in those thousands — because even if they were all to a local server, that's still terribly inefficient, and with latency it's even worse. Thanks!

In case it's helpful: we're going to make a new HN API that will be much easier to use. The idea is that adding something like "json/" to any HN URL will return a JSON version of that page.

Curiously enough, we should also be able to eliminate the pagination of comments by then as well. Both changes are waiting on some software work that we expect to improve performance significantly. I don't know when this will all be done, but I hope it's this year.
