The First Benchmarks Of Unity On XMir: There's A Performance Hit: With Thursday's announcement that Mir will ship by default in Ubuntu 13.10 on the desktop, many Ubuntu users were caught by surprise that this experimental display server will be ready by October. Up to now, Ubuntu 13.10 was expected to continue using an X.Org Server by default on the desktop (with only an experimental option for Mir) while the new Ubuntu Touch project would be using Mir on mobile devices, until next year. With the pressed timeline for the migration to Mir, at Phoronix we have already carried out our first Mir benchmarks. In this article are the first benchmarks of Intel graphics when running on Ubuntu 13.10 with a native X.Org Server (as done now on current Ubuntu Linux releases) and then when deploying the same Unity desktop environment atop XMir with the Mir unity-system-compositor.
