Thanks http.cache definitely improves this for caddy performance. I did quick test with non-HTTPS on virtualbox CentOS 7.3 compared with my Centmin Mod Nginx web server with siege 4.0.2 benchmarks and there is definitely a boost compared to plain caddy. Caddy http.cache had ~30.3% boost in performance (2,458 r/s) compared to normal caddy (1,887 r/s) but still behind Nginx for plain non-cached static html file request (between 3,373-3,605 r/s).
Noticed in http.cache mode, there’s duplicate Server: Caddy headers though ?
