There are no benchmarks in the virglrenderer repository.  Normal
graphics benchmarks (like glmark2, Unigine Heaven/Valley, webgl
aquarium) are used.  Depending on the benchmark, virgl is anywhere
from 20% --> 100% of native.

For benchmarking I recommend:

1) Use ToT virglrenderer and guest Mesa.  There's been some nice
performance patches lately.
2) Debug the slow benchmarks and send patches.  In the worst case, we
shouldn't be below 50% of native performance.
