I'm tunneling an HTTP connection over stunnel. The client side does not natively support HTTPS, so stunnel in client mode is used.
Would setting TCP_NODELAY=1 help responsiveness in typical web browsing? The way I understand it, Nagle's algorithm bunches up packets and sends data in whole multiples of the packet size.
My own benchmarking seems to have shown zero difference, though probably because my internet link to the server is too good.
