Just curious--why is HN run on only a single core?

Arc is implemented in Racket and uses its green threads, which don't do multiprocessing.

The standard Racket threads do run on a single core. Racket (not Arc) does however support two forms of parallelism, namely futures and places.

In my experience, the response rate is 100%. Responses are thoughtful, professional, respectful, and even friendly, and they obviously read through even longer messages. It's probably the best customer service of any organization I patronize, besides my attorney who charges a bit more. Given the number of users, the size of the staff and, knowing HN, probably users' demanding nature, I'm impressed. Not only that, but…

Sounds like Chuck Norris jokes to me

Hey, c'mon, you gotta admit, that cordless phone thing was pretty damn funny!

This is in the FAQ: https://news.ycombinator.com/newsfaq.html . If the unban link described there doesn't work for you, please email us and we'll take care of it. I'm sorry that this is necessary, btw. We hate it when legit users get blocked, but HN is also hit by a ton of crawlers and it's hard to distinguish the two. Since our app server runs on a single core, we don't have a drop of spare performance. Some big imp…

> Since our app server runs on a single core Wow. Couple of questions : * where is the server hosted and do you have a db server and maybe a cache server as well? What are the specs of the server? * how much traffic does HN receive? Daily or monthly hits. > Some big improvements which we've been working on for months will hopefully roll out soonish If you're allowed to talk about it, what are the improvements?

We’re recently running two machines (master and standby) at M5 Hosting. All of HN runs on a single box, nothing exotic:

  CPU: Intel(R) Xeon(R) CPU E5-2637 v4 @ 3.50GHz (3500.07-MHz K8-class CPU)
  FreeBSD/SMP: 2 package(s) x 4 core(s) x 2 hardware threads
  Mirrored SSDs for data, mirrored magnetic for logs (UFS)
We get around 4M requests a day.

Requests like these are better sent to hn@ycombinator.com, but note that they simply won't reply to you if they get busy or don't feel like it. From my testing, HN has various anti-abuse features to prevent people from creating accounts to dodge bans or moderation penalties. E.g. if you create an account using Opera's VPN, your account's comments will all show up as [dead]. Perhaps they believe that there's no valid…

In case anyone ever reads this, I should say that my description of my experiences were real. I added the last line because, reading it, the way I had written it sounded a bit overboard.
