Unity On XMir Performance For Nouveau Gallium3D

Unity On XMir Performance For Nouveau Gallium3D: On Friday I delivered the first benchmarks of Ubuntu's Unity desktop running on XMir -- the X.Org Server compatibility layer for talking to the Mir Display Server. Those benchmarks showered there was noticeable performance overhead to running XMir with Intel's graphics driver. Later benchmarks showed XMir 2D performance was also negatively affected. In this article are benchmarks looking at the XMir performance with the Nouveau driver.
