Re: [Xen-devel] Load increase after memory upgrade (part2)

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

I also have done some experiments with the patch, in domU i also get the 0% 
full for my usb controllers with video grabbers , in dom0 my i get 12% full, 
both my realtek 8169 ethernet controllers seem to use the bounce buffering ...
And that with a iommu (amd) ? it all seems kind of strange, although it is also 
working ...
I'm not having much time now, hoping to get back with a full report soon.
