I have around 7ghs at scrypt im with bitmain l3+ and im doing very low shares the guys with 3-4 gha are doing more than double shares? And also guys that are with my hashrare are getting much more shares than me. There is only 1 port i was looking if this is port problem but it isnt. We all are mining at the same port. How to fix that? Is bot enough internet? If someone help me to fix that im able to ddonate!
The amount of shares depends on difficulty you set. Other guys may have set a low diff (so giving a lot of shares but overall performance is less than yours .. so is the mining reward).
EDIT: if you are receiving around 0.25 LTC daily from each miner everything is fine.
