I'd wager a CGI written in C uses less memory and CPU than an equivalent application in any other language or framework. I'd wager this design has lower latency meaning higher throughput and therefore higher capacity, too.
Or perhaps you mean developer efficiency? Well, with the right tools you're going to catch memory issues so they're gone. It's a tiny language you can keep in your head, so that's not an issue - I'd argue you need an LLM to write good C (if you know what you're doing), than to write good Java or Python.
I sure do love a modern language and environment (I spent years as a Rails dev, and I love me a bit of Elixir), but to argue that C is not efficient is kind of wild.
