The performance would be notable. However, hardware is cheap these days.

> The performance would be notable. Can you quantify & explain what you mean by notable? I've written a lot of C++ and also a lot of scripted web services like node.js and flask (python). For most normal websites, I doubt that you could make significant and noticeable performance improvements to a decent scripted backend by switching to c++, from the user's point of view. A latency savings of a millisecond or two across the board I could buy, but making it obviously faster to a user, I'm skeptical, unless the site has non-traditional high performance requirements.

  What exactly is the "performance" you're talking about? How you define it?

    > What exactly is the "performance" you're talking about? How do you define it? You can see that that was precisely my question, right? Did you mean to reply to the parent comment? The article says the reason to use C++ over rails or node or another scripting language is "performance", the parent comment to mine said that the performance difference would be "notable". I'm asking exactly what you're asking -- what is performance, what is notable? On top of that, I did define performance loosely in my comment -- as something that is noticeably faster to the user. If a user running Chrome can feel the difference on a site, and the only difference is the language it was written in, then I could buy that C++ gives better "performance". I suspect it's rather difficult to write a custom C++ web server and make it load or run any faster, from the point of view of the person on the other end, than a generic rails/flask/nodejs web site, for most sites.

        Thanks. Yes. I said this very thing in my top comment. It takes a lot of users (many more than 10!) in any modern web server framework to get noticeable slowdowns, unless you've done something horribly wrong. So the question on the table -- still -- is what web applications might actually require a C++ web server, in practice?
