  • This patch adds a service time oriented dynamic load balancer,
    dm-service-time, which selects the path with the shortest estimated
    service time for the incoming I/O.
    The service time is estimated by dividing the in-flight I/O size
    by a performance value of each path.

    The performance value can be given as a table argument at the table
    loading time. If no performance value is given, all paths are
    considered equal.
