Shuttleworth, CEO of Canonical (Ubuntu system sponsor), reiterated the practical benefits of this speed advantage. "The Canonical company provides users with a commitment to kernel and user space efficiency, ensuring that they can support everyone to create a container system with the same actual effect as the virtual machine, in addition, even common non-root users can enjoy the same experience as the root user of the virtual machine in the system.
