And without having done any proper benchmarking, hitting any of these rendered type pages after that just feels much slower and less fluid on Nginx. I am really surprised!

You can try to increase number of worker_processes, say to 4-8 and
turn off sendfile. Also, I can not say how theses third-party modules
may affect in perfomance:

--add-module=/build/edmonds-nginx_1.0.4-1~bpo60+1-amd64-oC2LKI/nginx-1.0.4/debia
n/modules/nginx-development-kit
--add-module=/build/edmonds-nginx_1.0.4-1~bpo60+1-amd64-oC2LKI/nginx-1.0.4/debia
