If everything is just about performance write your whole stack from scratch in assembly. See how that goes ;) The authors point is some sites will come up plenty fast enough on Caddy. Use what's best for your scenario. I don't use it myself but it seems like a good option.

For last 15-20 years it's very hard (if at all possible) for human to beat compiler optimization in real life tasks. So, your advice has little sense.

Sure, if you are just using it for your personal site, the performance difference shown in the benchmarks, doesn't matter at all. If you are running a relatively popular web-shop, it matters a lot.

"Amazon’s calculated that a page load slowdown of just one second could cost it $1.6 billion in sales each year. Google has calculated that by slowing its search results by just four tenths of a second they could lose 8 million searches per day–meaning they’d serve up many millions fewer online adverts."

Uh, it was supposed to be a joke about worrying about every single performance optimization for a web site that may have very little need. People still use Wordpress and other "fat" CMS's etc. without a problem...

Well, we're draining planet resources without a problem as well. And affecting climate without a problem too. Does that mean that we should not worry about these issues at all, if they don't cause any problems to us?

You're totally right that we should consider the efficiency (and therefore energy + cost) aspect. But it can't be the only thing we consider. If two options are equal in all respects except efficiency, there can be no question that we would choose the less efficient option.
However, if for example configuration is simpler, and managing SSL certs is very important, then it might make sense for someone to choose a less efficient option that has those other advantages. I'm sure you've run into configuration problems that wasted hours of your time -- that could be enough to cancel out the cost savings of the more efficient option.

Completely agree. I just answered on an attempt to downplay importance of efficiency.

Funnily enough Caddy handles medium load more efficiently than NGINX, with much lower times to first byte on average, and with much less CPU consumption. Matt (the project author) made the same findings and dropped them in a thread on the Caddy forums.

Performance is not the only factor to take into account though when building good software, and whilst C or the likes will outperform many languages when counting the Fibonacci sequence, it can't compete with the Go ecosystem when it comes to networking tools. Hell, Netflix uses Go for a huge part of its networking stack, and they boast one of the largest, most complex setups to date.

I'm all for questioning new or "hype" projects, but it's unfair to describe Caddy as such. NGINX is very dated, and whilst it performs fantastically in specific use cases, it's good to have a new alternative that's more forgiving in the many new challenges we face today.

Well, taking into account that vast majority of networking code across all operating systems is written in C or C++, Go ecosystem is more or less usable at best. And I know what I'm talking about because at one of my previous jobs I was writing networking tools in Go.

I came across your comment recently, on the other hand, comparing static HTML/dynamic content seem it's a good replacement for PHP-FPM+Nginx with just Go that gave more than 3x performance on a VPS with 1vCPU. At least, that the next logical step to consider since you are probably aware majority of websites on shared hosting are running PHP. Overpaying for lower performance efficiency is bad.
