No matter how much you can do with a single thread, in a highly parallel environment (such as a web server), on a cpu with multiple cores (the norm), you can (almost always) do more with multiple threads.
Ok, I understand why you might "offload" read() from disk backed files file descriptors. But why "sendfile"? I thought sendfile is properly async in linux... Unless I'm getting something wrong. "aio_write" -> wasn't the idea of AIO operations to actually be truly async? Maybe it's because it requires XFS. Anyway, I'm confused.
"The page cache works pretty well and allows NGINX to demonstrate great performance in almost all common use cases...So if you have a reasonable amount of RAM and your working data set isn’t very big, then NGINX already works in the most optimal way without using thread pools"
So using thread pools in NGINX isn't a general recommendation. The article suggests "a heavily loaded NGINX‑based streaming media server" as the type of situation where it makes sense.

The moral is that threads and asynchronous programming are not mutually exclusive. No matter how much you can do with a single thread, in a highly parallel environment (such as a web server), on a cpu with multiple cores (the norm), you can (almost always) do more with multiple threads.

Sure for threads up to cores / 2. Past that it is likely a throughput and latency loss.

Does anyone have numbers to back this claim? Seems like for IO focused software you'll have a lot of dead CPU time. If you have more threads than cores, you can take advantage of that.
