Bug#520928: linux-image-2.6.26-1-686: PIIX4 /dev/hda performance regression (10x times, DMA dissabled)



Hi.

I tested for a week kernel 2.6.32-5-686-xen on xen 4.0 from squeeze.

Essentially perfromance is still very bad. It is slightly better (about 2-2.5 MB/s,
instead of 1.5 MB/s), but still makes this useless). One still cannot even enforce
using DMA.
