Has anybody measured the cost of enabling or disabling verification?

The cost of disabling verification is an infinitesimally small number
multiplied by possibly all your data.  Basically lim->0 times lim->infinity.
This can only be evaluated on a case-by-case basis and there's no use in
making any more generalizations in favor or against it.

The benefit of disabling verification would presumably be faster
performance.  Has anybody got any measurements, or even calculations or
vague estimates or clueless guesses, to indicate how significant this is?
How much is there to gain by disabling verification?


Exactly my point and there isn't one answer which fits all environments.
In the testing I'm doing so far enabling/disabling verification doesn't make any noticeable difference so I'm sticking to verify. But I have enough memory and such a workload that I see little physical reads going on.
