Log:
  8115 parallel zfs mount
  
  Mounting of filesystems in "filesystem/local" is done using `zfs mount -a`,
  which mounts each filesystems serially. The bottleneck for each mount is
  the I/O done to load metadata for each filesystem. As such, mounting
  filesystems using a parallel algorithm should be a big win, and bring down
  the runtime of "filesystem/local"'s start method.
