  >got a source for this stackoverflow peak? 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. [1] https://stackexchange.com/performance https://stackexchange.com/performance

    > Sub 20ms response time with zero caching. 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.
