2D Performance Also Impacted By Unity On XMir

[mark45]

But what's the 2D performance on pure Mir? Faster, same, worse than on X.org?

After all, we're all looking forward to use pure Mir or Wayland as much as possible, with X.org on top of them as little as possible.

Phoronix: 2D Performance Also Impacted By Unity On XMir

Earlier today I delivered the first benchmarks of Ubuntu's Unity 7 running over XMir to run the current X11 desktop atop the Mir Display Server via this compatibility layer. These benchmarks documented the performance impact of running OpenGL games when having to deal with XMir rather than just a clean X.Org Server running on the hardware. The extra step in the rendering process did result in a measurable performance impact, especially when the performance of the open-source Linux graphics drivers is already lower than their proprietary brethren. The benchmarks to now show illustrate that the 2D rendering performance also takes a hit when running Unity on XMir.
