Overly complex and feature-filled (or extremely barebones and "fast") frameworks can also have the property of giving no responses for additional months at a time. (i.e., sometimes "it works" is good enough, and our ego in design elegance doesn't need to get in the way of our need to keep existing as a business. If we need to rebuild or refactor later when we really know what we want, we can. :) )
It is [1] ( and should be ) pretty well known. 1.3 BILLION page view per month, 6K RPS with 9 ( Fairly Weak ) Servers, Sub 20ms response time with zero caching.
>also wondering what peak RPS is for HN.
Less than 100 RPS for logged in users. The number were pre 2020 but I doubt the current number is significantly higher.
I mean... to be clear, they do tons of caching[0], which is certainly critical for their ability to have a non-cached response time of 20ms. Most of their responses should be coming from a cache, given the type of site they run, otherwise they would need a lot more servers.
