We should meter all of these, yes.

However, I discagree that the no-DNS case is the important one.  The vast
majority of ordinmary users go to the pool. It's the hand-tuned setups that
are the exception.

Thus, the most urgent bug right now is clawing back the performance lost in
"DNS bug fixing/cleanups". Please give that priority.  Tuning the other cases
(and fixing iburst so that it's no longer a no-op) can wait.
