Compare WU for absolute differences. U is a relative figure based on target diff.
anyone?
so which is more important?
higher hash rate ?? or higher utility rate ?? higher utility gives faster Accepted shares.
higher hash rate ?? or higher utility rate ?? higher utility gives faster Accepted shares.
Err. Wait. So the miner with a lower difficulty and higher hashrate is sending LESS shares?
The idea behind share difficulty is to reduce bandwidth costs for all involved. Basically, by sending you more difficult work, they don't need to send you as much. A higher-powered mining thread should thus have more difficult shares so it isn't sending as much work. A more difficult share receives a higher reward than a less difficult share, so it's supposed to roughly balance out. (think of increasing difficulty as increasing voltage, decreasing current, and maintaining the same power)

Hi guys, im currently mining LTC. Both machine are using the same card (Sapphire HD 7950).
However they both yield different results.
my first machine is running ~345 Kh/s and getting U: 3.35/m simply by using this setup:
my second machine is running ~600 Kh/s but only getting U: 2.4/m which uses the follwing code
note U: The Utility defined as the number of shares / minute
My question is, why does slower hash rate produce higher utility rate ?? is this common ? or im doing something wrong here??
arent hash and utility rate suppose to be proportional to each other??
the only difference that i can observe is machine#1 is doing diff 96 and machine#2 is doing diff 34.
any help would be much appreciated it.
