I've heard this argument a lot, and have even used it myself as a justification for using Ruby on Rails over other technologies, because I like working with Ruby. However, I rewrote one of my large CRUD applications in Elixir and Phoenix a year or so ago (same database and same data) and was amazed at how fast my web app was when compared to the Rails version. I've had similar experiences with the Crystal code I've written (replacing vanilla Ruby), so I've had to step back from this argument and admit it isn't entirely valid. I don't say this to knock Ruby. I love Ruby and think Matz is an outstanding human being. I'm just pointing out that while the database server can be a bottleneck, to be sure, there are still plenty of benefits to using faster languages to accomplish database-centric tasks.
