It seems useful and added performance: SSL Termination for TCP Upstream Servers | NGINX Plus
Centmin Mod uses SSL session caching by default so should suffice Code (Text): cat /usr/local/nginx/conf/ssl_include.conf ssl_session_cache shared:SSL:10m; ssl_session_timeout 60m; ssl_protocols TLSv1.2 TLSv1.3; Using session tickets requires you're regularly rotating the session ticket keys for security which that article you linked to doesn't even outline the specifics for. If you have a multi web server cluster too, you'd need to account for that across all Nginx servers too.
