I am using the 3.12. So the cpu utilization (top output) of vifx.0 process in dom0 is for data copy and irq processing, right? I found that if the vif irq processing is on the same core where the corresponding domU is running, the CPU utilization of dom0 is lower and the application IOPS is higher. I think maybe it is caused by less IPIs are issued. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
