The rejected shares are the number of shares rejected by DxPool because those shares don't meet the requirement of servers. The rejection rate is the ratio of the rejected shares number compared with the total submitted number. The smaller the rate, the higher the mining efficiency. The rejection rate in major blocks is usually below 1%, minor blocks' rejection rate can go higher.
High rejection rate usually affected by unstable internet connection; here are some examples:
- Miners under the same internet switch all present high rejection rate, inspect the switch for malfunctionings.
- One particular miner presents high rejection rate, replacing the cable may slove the problem.
