Dear All, I am doing some disk io performance testing on the following environment: Dell AMD R515 with: - debian6 (2.6.32) on host and guests. - raid1 mirror on a perc h700 - lvm used to create virtual disks volumes - virtio enabled per default on 2.6.32 and used for nic and disk drivers For my tests i use the following command: dd bs=6M count=500 if=/dev/zero of=toto.txt On local host i get 500MB/s On 1 guest 150MB/s On 2 guests in parallel 70MB/s Here are my questions: 1) Is this the expected behavior ? 2) What can i do next to improve local disk performance ? 3) If i want to do shared storage with best disk io performance, what kind of storage should i use ? Thanks in advance :D Benoit. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
