It sounds like you may have a Newton solver now for each individual problem? If so, could you make a histogram of number of iterations necessary to solve? Does it have a long tail or does every problem take 3 and 4 iterations (for example). If there is no long tail, then you can batch. If there is a long tail, you really want a solver that does one problem at a time, or a more dynamic system that checks which have completed and shrinks the active problem down. (That complexity has a development and execution time cost.)
