Sure, please provide a patch, that does not break back pressure. But just in case, if Xen performance relied on bufferbloat, it might be very difficult to reach a stable equilibrium : Any small change in stack or scheduling might introduce a significant difference in 'raw performance'. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
