Ask HN: What's the datastore behind HN?
18 points by klochner on Nov 9, 2010 | hide | past | favorite | 6 comments
I've noticed that the front page loads significantly faster than the threaded comments page.

I'd be interested in a discussion as to what causes the relative slowness of the discussions.

Is it just homepage caching?



S-expressions stored in files, lazily loaded, and occasionally gced.

There are many levels of caching, but it could simply be that the homepage has 30 things on it while a threads page might have hundreds.


PG, may I distribute my scrape of HN?


I don't personally have any objection to it but it sounds like some users do.


Why not move to Java EE 6 platform?


The original raison d'etre of HN was to exercise the one it's built on.


I was actually just trolling after a few beers. I know the story behind HN.
