I served 120k requests from may, 10th to today from an old dell optiplex fx 160 (choosen in 2017 from this article [0]), which have a poor intel Atom processor & 3Gb of ram.<p>I have between 1000 & 4000 hits per day (from 400 to 600 visitors, mostly bots I think), so not really millions of users.<p>The websites hosted on this computer varies from a very simple php website [1], a service that's kinda like Shaarli [2], txt pages for when I share content to websites with heavy traffic [3] (hello HN[4]!), to a dead simple html page [5] (that's where all the bots traffic is coming I think, they really like xyz domains, but I love the fact that I'm able to say "one 2, three 4, five 6" when speaking about my domain :)).<p>[0] <a href="http://thesizzlewo.webflow.io/blog/get-a-dell-optiplex-fx160-instead-of-a-raspberry-pi" rel="nofollow">http://thesizzlewo.webflow.io/blog/get-a-dell-optiplex-fx160...</a><p>[1] <a href="https://l3m.in/" rel="nofollow">https://l3m.in/</a><p>[2] <a href="https://links.l3m.in/" rel="nofollow">https://links.l3m.in/</a><p>[3] <a href="https://misc.l3m.in/txt/" rel="nofollow">https://misc.l3m.in/txt/</a><p>[4] <a href="https://news.ycombinator.com/item?id=28468977" rel="nofollow">https://news.ycombinator.com/item?id=28468977</a><p>[5] <a href="https://244466666.xyz/" rel="nofollow">https://244466666.xyz/</a>
"millions of users" depends on the service, doesn't it? im sure you could serve random integers to millions of clients with quite modest hardware, would that count?
