Cloudflare really doesn't make much of a difference for HN. The last front page traffic I saw (~a week ago?) was still at most a handful of QPS. Any nginx instance with default configuration serving static files from any modern computer should be able to handle that (given that your link is big enough).
Now if you reach the top of a large subreddit, or have a viral tweet with a link to you, that's a different order of magnitude. HN is just not that large.
- aaaaaaaaaaab 5y agoThen why do people talk about the "HN hug of death"?
- brightball 5y agoIf you’ve got a bunch of images and your site is running uncached with a clunky CMS behind it, it will probably strain you. The traffic is usually about 40k uniques over 24 hours. For reference, my uncached site is running on Elixir which is often better without caching.
- ComputerGuru 5y agoIt’s usually not images but rather the CMS making 100 read queries and 20 write queries per page load without any object caching that brings sites down. Even a slow uplink serving big image won’t bring an nginx server down, it’s all async.
- brightball 5y agoServing a lot of images at the same time will work the disk I/O up in many cases. Probably gotten a lot better with NVMe though.
- ComputerGuru 5y agoIt’s typically one page that hits Reddit/HN/whatever with its fixed set of static images. It’s pretty much the ideal scenario for the kernel’s in-memory cache.
