Most people who are mining, are only looking at the reported hashrate by the miner software – and this could be an expensive mistake! There are a few factors that makes the real, average hashrate on the pool side – the hashrate you are actually getting paid for – are lower than the reported hashrate.

The fee to the miner softwareAlmost all miner software, a fee are sent to the miner developer. This is normally between 0.5% and 1%. If you are mining with a reported speed of 500 Mh/s, this will reduce the average pool hashrate with between 2.5 and 5.0 Mh/s
Shares that are not acceptedInvalid and stales share are shares that you will (normally) not be paid for, by the mining pool. A top notch miner has both a DAG verification and a DAG repair function, to reduce the risk/number of invalid shares. Also the internal latency of miners have a big impact of the number of stale shares. This could, in extreme cases, make up to a few % of your total hashrate are lost, since the miner software adds a big latency before the share are submitted to the pool.

Overreporting minersThe most controversial topic, are that actually most miners over-reporting the hashrate. The reason miner developers do this, are of course to attract users. Higher numbers, must be better right? Our benchmark tests, shows that many miners are over-reporting with 1-2%, while there are good, honest miner software with true hashrate – there are also some really bad examples!

So what should I look at?Look at the average hashrate on the pool, this will tell you what you are actually getting paid for. Be be aware - you really need a minimum 50.000 shares for this number to make any meaning statistically. Thats the reason we are doing all our benchmarks with a minimum of 1.000.000 shares!
