--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
There isn't much I can do since that flush is required to workaround a hardware
issue.

On my mobile systems (i3-330), the degradation is closer to 10%,
7.9Mglyphs/s to 7.3Mglyphs/s, which is not that worrying.

Can you please describe how you avoid the IPS penalty on Ironlake for
benchmarking?
