Minimizing NExpectation for a custom distribution in Mathematica
...
As far as I see, the problem is (as you already wrote), that MeanResidualLife takes a long time to compute, even for a single evaluation. Now, the FindMinimum or similar functions try to find a minimum to the function. Finding a minimum requires either to set the first derivative of the function...

I have searched for answers, but they all seem to suggest using the clock() function, which then involves calculating...
