> Performance is often FUD when it comes to languages. Not in my experience. All other things remaining constant, the D Language forums (written in D) are significantly faster for me compared to almost any other forums I visit (including HN, any PhpBB stuff, Stackoverflow, etc.). I also think that the statement, often made online, that web application performance is limited by network performance and not CPU performance, is absolute BS. My previous statement is an example of that.

There are so many things that could account for performance differences in forum software, pointing to the language as the cause without knowing them all is less than useless, it's borderline misleading. Here's just a few of the things that can affect performance between different forum software written in the same language: Database schema, database software, database server resources, number of forum users, number of forum posts, average forum posts a day, number of forums viewers that are not users, webserver(s) resources, whether the webserver(s)/database server share resources with each other or other services, extra features supported by one forum and not the other, the network connection between the webservers and database server, the network connection between you and the webserver(s).

  Upvoted. However, you provide great arguments why blindly assuming that performance does not matter and just "throw more cores at it" is not a viable solution.

  Not borderline misleading. It's completely absurd.

You're comparing a custom forum written in a pet low-level language to PhpBB and concluding that the language is the reason for the performance difference? Clearly you have a lot to learn about web application performance.

  One of the reasons, not the sole reason. The point I was trying to make is that "just ignore performance and use an expressive language" is not always a sound strategy - even for web applications. And yes, my example is probably a poor one.

    D Lang forums have probably never seen the amount of traffic that those places get, for one, so you haven't actually experienced it though.
