Q: The Queue never increases on my card but the efficiency keeps going up, how
can the efficiency be so high?
A: Efficiency is defined as the accepted shares returned over the number of
work items requested. Cgminer generates a lot of work locally, and has a
buffer of "global" queued work meaning the device may hardly ever be requesting
work itself. Thus the number of work items requested may be very small yet the
GPU may still have plenty of work, creating accepted shares from them. Thus the
"efficiency", by that definition, becomes extremely high.
