From cgminer I see that I get tons of Locally Generated Work Items = LW:-number is high.
I've searched and searched for weeks. I found only one occasion that said it to bee really good thing, but nothing
more.

So is it a good thing?
What does it actually mean, and how come it is such a good thing?
Please give as much information as possible, since there are nowhere to find any.

If it is such a good thing, how to increase it/ lower it?

Thanks in advance.
