20% is about the general order of magnitude we observed in FEX a while ago, though as you enable all TSO compatibility settings (including those rarely needed) it'll be much higher even. As people elsewhere in the thread mentioned it'd be interesting to see how FEX fares on Asahi with hardware TSO enabled vs disabled (but with conversative TSO emulation as set up by default) since it's less of a blackbox.
