How about the performance vs nginx?

[lunny]

It's a new great product about Golang. But I want to know how about the proformance with nginx?

That's ultimately for you to decide. Web servers are complex enough that benchmarks measure configuration and the host system itself more than code performance. That is, for benchmarks which measure req/sec.

There are unit-level benchmarks which are much more telling, but these can be less useful when you want the big picture.

However, because this is a common question, I've published some very unscientific benchmarks on the FAQ page (near the bottom). I've repeated the tests with a few differences every time and the results on my system are fairly consistent: Caddy and nginx are comparable in speed, although nginx is a little faster. This is expected. Caddy is fast enough for most sites, and with time, Caddy can be made faster with internal tuning.

We'd welcome any contributions to improve Caddy's performance!
