ed3eb5771a Introduce a new statistic, Work Utility, which is the number of difficulty 1 shares solved per minute. This is useful for measuring a relative rate of work that is independent of reject rate and target difficulty. 2012-08-18 15:44:48 +10:00

26ab7346e3 Implement a new pool strategy, BALANCE, which monitors work performed per pool as a rolling average every 10 minutes to try and distribute work evenly over all the pools. 
Do this by monitoring diff1 solutions to allow different difficulty target pools to be treated equally, along with solo mining.
Update the documentation to describe this strategy and more accurately describe the load-balance one.
