very interesting! it seems that IDE wins on all the performance numbers, but VirtIO always has lower CPU utilization. i guess this is guest CPU %, right? it would also be interesting to compare the CPU usage from the host point of view, since a lower 'off-guest' CPU usage is very important for scaling to many guests doing I/O. -- Javier -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
