Why pool shows less hashrate than miner?

  1. Please judge it by the pool 24 hours hashrate value, mine constantly over 24 hours and make a comparison between the local and web hashrate then.
  2. Please check and confirm if it is caused by the network delay, severe overclocking, high HW, mining hardware failure.
  3. If for ASIC miner, please try to “Ping” our pool address and see if the connection is good.
  4. The miner machine’s hashrate is too high, the mining difficulty mismatches.
