We are trying to decide whether to use filesystem or LVM for VM storage. It's not that we are happy with LVM - while it performs better there are limitations on LVM side especially when it comes to manageability (for example certain features in OpenStack do only fork if VM is file-based). So, in short, if we would make filesystem to perform better we would rather use filesystem than LVM, (and we don't really have any special requirements in terms of filesystem features). And in order for us to make a good decision I wanted to ask community, if our observations and resultant numbers make sense.
