It mostly affects the performance of long unidirectional streams (file transfers) whereas the X protocol, as far as I know, is a bidirectional exchange of relatively short messages. It may make a difference for applications that transfer large textures... I don't really know enough about the X protocol to say for certain, but I am typing this in Emacs over a non-HPN SSH connection, and I regularly tunnel Firefox between the same two machines (RHEL 7 desktop at work and FreeBSD 10 desktop at home).
