I've been playing with comparing nginx and stunnel and in my scenario, nginx is much more flexible but performance is much worse than with stunnel. Connections to stunnel respond back within a couple of seconds. Nginx sometimes takes 10s of seconds to connect. I have them both set as windows services so I can switch between them easily.
My CPU is an older Core i5 750 which was satisfactory for the stunnel configuration but not the nginx configuration.
The two nginx features I really like are:
- rewrite any http connecions to https automatically
- allow me to configure LetsEncyrpt free certificates and install them
but I can't afford the performance penalty.
I'll just have to use nginx when I neeed to refresh my LetsEncrypt certs then switch back to stunnel for day to day operations.
