So, I get the frustration expressed here, but PH-K just comes off sounding like an arrogant prick by the end of this. I know I'm supposed to attack the argument and not the author, but it's very hard to read a piece like this when the author makes you feel like he's talking down to you the entire time.<p>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 (<a href="https://news.ycombinator.com/item?id=13226341" rel="nofollow">https://news.ycombinator.com/item?id=13226341</a>). 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.
