Issue with Nanopool

[UnamSanctam]

Yeah Nanopool has quite a delay but the amount of shares don't directly correlate with hashrate or mining speed. The amount a share is worth depends on the share difficulty of the jobs sent by the pool. Nanopool has a fixed 480 000 share difficulty while MinerGate has a dynamic difficulty that starts with 1000 meaning that one Nanopool share is worth the same amount as 480 starter MinerGate shares (this depends though on how Nanopool and MinerGate chooses to show shares, sometimes the shares they show aren't really the shares you mined but instead they split the share you mined into several shares in the statistics). It should be using RandomX since that is the only algorithm used by Monero but I believe MinerGate just hasn't updated anything since the algorithm change in the beginning 2020.

Look at the hashrate and not the shares, since Nanopool has a fixed difficulty of 480 000 then mining one share with 1000 H/s would take 480000/1000/60=8 minutes on average but it would be worth more than a share with lower difficulty.

[UnamSanctam]

You should check the average hashrate over 1/2/3/6 hours on both of them to be able to see the difference clearly due to the luck based nature of mining.

There has been enough tests in my opinion to ascertain that they do steal hashrate. The XMRig devs also warn you to not use MinerGate for that reason.

That is also one reason, and no it's not necessary, those are just libraries that get built together with XMRig.
