--- Comment #10 from Chris Wilson <chris at chris-wilson.co.uk> ---
As a point of reference:

=0 ickle:/opt/xorg/src/intel-gpu-tools/tests$ time sudo ./gem_tiled_swapping 
IGT-Version: 1.7-gd0dc2c5 (x86_64) (Linux: 3.16.0-rc5+ x86_64)
Using 9598 1MiB objects (available RAM: 7558/7905, swap: 6773)
Subtest threaded: SUCCESS

real    13m6.927s
user    0m3.881s
sys     4m17.993s

Using 2x the amount of data, my machine is about 4x quicker. An order of
magnitude difference suggests machine configuration - but just maybe it is
worth restesting.
