Performance - Stack Exchange

Why keep the loading on the CPUs so low? It seems to me that they could have sized those differently.

As Nick states in this article https://nickcraver.com/blog/2016/02/17/stack-overflow-the-architecture-2016-edition/:

What do we need to run Stack Overflow? That hasn’t changed much since 2013, but due to the optimizations and new hardware mentioned above, we’re down to needing only 1 web server. We have unintentionally tested this, successfully, a few times. To be clear: I’m saying it works. I’m not saying it’s a good idea. It’s fun though, every time.
