Absolutely awesome! I have recently gave Caddy a shot, and immediately loved it!. I am a bit worried about the performance deficit compared to apache or Nginx, but none of my servers really have reached the scale where it actually matters. Its unfortunate that there is no dynamic brotli support, but oh well, a trade off I'm willing to make. One of things that aren't clear to me are Caddy plugins. How big of an affect do they have on peformance? Are plugins a core part of Caddy's usage? Or are they just exist to cover some edge cases? I'm thinking of using the caddy-filter and caddy-crowdsec-bouncer plugins.

Having plugins installed has no performance incursion at all (because they don't run unless configured), but using them will, of course affect performance. But it depends on the plugin and what it does. You have to do your own benchmarking to see what effect they have to performance. Everyone has different needs and configs, so it's not possible to give authoritative benchmarks. Just try it out and see. Regarding brotli, there is a plugin you can try if you'd like https://github.com/ueffel/caddy-brotli https://github.com/ueffel/caddy-brotli, but brotli's on-the-fly performance is not that good. It works well if you pre-compress you assets though, and you can serve those with the file_server directive's precompressed option.

Glad you liked it! Caddy's performance is competitive with nginx, but there are too many dimensions to discuss here. I guarantee that for most people, your web server will not be your bottleneck. Dynamic brotli is expensive, as brotli compression is inefficient. There are no optimized Go implementations of this yet. But Caddy can serve precompressed brotli files without any separate plugins. What do you mean by "what affect do [plugins] have on performance"? All features in Caddy are plugins, some just come installed by default: https://caddyserver.com/docs/architecture https://caddyserver.com/docs/architecture -- even its HTTP server is a plugin. (All plugins are compiled in natively.)

Oh I didn't know that, thanks for the awesome project!
