看到 Ask HN: Is Hacker News slow for anyone else? 這邊的討論,dang (Hacker News 的管理員) 在 35157344 這邊就有出來說明:
All: our poor server is smoking today* so I've had to reduce the page size of comments. There are 1500+ comments in this thread but if you want to read more than a few dozen you'll need to page through them by clicking the More link at the bottom. I apologize!
Also, if you're cool with read-only access, just log out (edit: or use an incognito tab) and all will be fast again.
* yes, HN still runs on one core, at least the part that serves logged-in requests, and yes this will all get better someday...it kills me that this isn't done yet but one day you will all see
另外比較特別的是,Hacker News 是用 Arc (Lisp) 寫的,不過看起來沒有考慮到 optimization,加上那天 Reddit 也掛了,的確帶動 Hacker News 這邊更新的頻率比較高...
