Understanding the Solve mecanism

I'd like to understand how the Solve tool works when it's looking for an itinerary on a NA Route layer where each segment has a cost. What is the algorithm that Solve uses?
I'd like to optimize my model: the idea I have is to create a buffer around the stop locations in order to limit the number of route segments around the stops. Then, execute the Solve tool on that buffer area. Would it make the solve operation quicker?
Is there any difference (in terms of processing time) between a Solve performed on a small network and a Solve performed on a bigger one?
