Hi, I'm using KVM, and the virtual disk (a 20 GB file using the "raw" qemu format according to virt-manager and, of course, placed on a btrfs filesystem, running the latest mainline git) is awfully slow, no matter what OS is running inside the VM. The PCBSD installer says it's copying data at a 40-50 KB/s rate. Is someone using KVM and having better numbers than me? How can I help to debug this workload? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
