I agree. What I am mostly looking for is the best setup
for using KVM snapshots:
KVM qcow2 on top of something like ext4 or
raw on top of btrfs

I am going to try to benchmark a couple variations and flags
qcow2 on ext4 (noatime)
raw on btrfs (defaults)
raw on btrfs (noatime,space_cache)
raw on btrfs (noatime,nospace_cache)
raw on btrfs (noatime,nodatacow)
Any other options that might be good to try?
