I tried it. Performance was awful with the standard XQuartz client, especially scrolling, so I tried some alternatives: TigerVNC, X2Go, NoMachine, RDP. NoMachine had the best performance by far, RDP was decent. VNC and X2Go were too fiddly to setup for my.
Even with NoMachine the overall experience was clearly much worse than a native browser (mostly due to worse trackpad-scrolling).
Aw, that's disappointing! This was over wired lan?
I'm very surprised that standard render-remotely-and-send-pixels software was more effective than X forwarding, where the drawing is still done locally.
