OTOH my limited experience suggests that the majority of front-page articles will get reposted several times.
Or someone could publish a "Best of HN" collection, then change all reposts to link to that.
I assume this was posted because of the presence of antirez's 4-years-later rebuttal (well, for some workloads) that's also on the front page today (https://news.ycombinator.com/item?id=13226341). It's interesting to see the difference in writing style: antirez seems to just aim to educate, and reasonably points out how redis's needs and memory access patterns don't allow for good performance if it were to just rely on the OS's VM system. The article about Varnish, however, comes off as someone telling us how stupid we are for not knowing how hardware actually works.
