iirc, which is huge.)
So i havent seen any real progress on reducing native kernel
overhead with paravirt. Patches were sent but no measurements
were done and it seemed to have all fizzled out while the dom0
patches are being pursued.
Hm, I'm not sure what you want me to do here. I sent out patches, they
got merged, I posted the results of my measurements showing that the
patches made a substantial improvement. I'd love to see confirmation
from others that the patches help them, but I don't think you can say
I've been unresponsive about this.
