Recommended miner settings

# During space-race-1 we tuned the dealbots frequency to not overwhelm the miners
# With space-race-2 underway your miner will be negotiating deals with a number of
# clients, who lack coordination among themselves. Therefore it is *very strongly*
# recommended to tune your miner parameters based on the sealing capacity you already
# known from space-race-1
#
# The numbers below are the bare minimum for a single-box, non-gpu miner, and are
# very conservative safe numbers. No doubt your miner can do better so you can bring
# these numbers up. But! Do not dial them too high: if you lose sectors due to an
# unresponsive miner, your clients will be... sad.

[Dealmaking]
  # This number is critical - the miner will not accept any deal that starts earlier
  # than the specified time. It equals the sum of
  # - WaitDealsDelay above
  # - The amount of time it takes your rig to go from Packing to Proving
  # - Any additional time you want to allow for contingencies
  # A conservative number of 24h is ok: clients expect this. Also if you seal the deal
  # faster - they will be able to retrieve it before the official deal start!!!

  # While we recommend trying to accept deals from anyone, it is good to have an
  # "emergency valve" to keep some bad actors out. By using the short program included
  # you do not have to even restart your miner: just edit the script and lotus will know
