export your $DISPLAY with X11, Citrix stole the idea. not many really do it anymore it seems, and i doubt Wayland does it at all.. works great for me

  ssh -x does that, _and_ it sets up authentication, making it harder to blow your foot off. No need to reinvent the wheel.

    And it kills performance, making you watch redraws, while sshd is maxing out a single core.

      The drawing is local to your machine, so it doesn't have any overhead over exporting $DISPLAY, and several sshd implementations have moved to fully multithreaded, since at least '08. The only performance hit is X11 (no different than normal) and the network - not ssh.

        Doesn't fit with my experience. Moving from using ssh -X to just pointing remote X applications at my local X server without tunnelling it over SSH consistently improves performance for me. Not just in terms of experience, but also no process maxes out a CPU, so the machine has spare compute capacity for other tasks. It's really not an issue of ssh not being multithreaded. That shouldn't happen even on a single core. If sshd divided that workload over my n cores, it would still be very bad.
