glxgears under classic is definitely not pinning the hardware -- the 'intel_idle' tool shows that it's only using about 70% of the GPU. GEM is pinning the hardware. Usually this means there's some synchronization between the CPU and GPU causing each to wait part of the time while the other executes. I haven't really looked at the non-gem case though; the numbers seem similar enough to what I've seen in the past. > I think getting reproducible results makes a lot of sense.
