ZFS, BTRFS, XFS, EXT4 and LVM with KVM – a storage performance comparison

Virtual machines storage performance is a hot topic – after all, one of the main problem when virtualizing many OS instances is to correctly size the I/O subsystem, both in term of space and speed. Of course performance is not the only thing to consider: another big role is played by flexibility and ease to use/configure. So the perfect storage subsystem is the right compromise between performance, flexibility and ease to use. In a somewhat ironic manner, of the three requisites written above, performance is the most difficult thing to measure, as“I/O speed” is an ephemeral concept. It is impossible to speak about I/O performance without taking into account three main parameters: I/O block s
