  # default: 8001
  downloadPort: 8001

  # SystemReservedBandwidth is the network bandwidth reserved for system software.
  # default: 20 MB, in format of G(B)/g/M(B)/m/K(B)/k/B, pure number will also be parsed as Byte.
  systemReservedBandwidth: 20M

  # MaxBandwidth is the network bandwidth that cdn can use.
  # default: 1G, in format of G(B)/g/M(B)/m/K(B)/k/B, pure number will also be parsed as Byte.
  maxBandwidth: 1G

  # AdvertiseIP is used to set the ip that we advertise to other peer in the p2p-network.
  # By default, the first non-loop address is advertised.
  advertiseIP:

  # FailAccessInterval is the interval time after failed to access the URL.
  # If a task failed to be downloaded from the source, it will not be retried in the time since the last failure.
  # default: 3m
  failAccessInterval: 3m

  # GCInitialDelay is the delay time from the start to the first GC execution.
  # default: 6s
  gcInitialDelay: 6s

  # GCMetaInterval is the interval time to execute GC meta.
  # default: 2m0s
  gcMetaInterval: 2m

  # TaskExpireTime when a task is not accessed within the taskExpireTime,
  # and it will be treated to be expired.
  # default: 3m0s
  taskExpireTime: 3m

  storageMode: disk

  # logDir is the log storage directory
  # in linux, default value is /var/log/dragonfly
  # in macos(just for testing), default value is /Users/$USER/.dragonfly/logs
