Scaling of range raptor by number of minutes searched #23

gmellemstrand commented 5 years ago

I have tested how multicriteria range raptor scales with the number of minutes searched. The test loops through the same search and increases the search range by one minute for each iteration. What is interesting now and when more optimizations are added is how long it takes to set up the search and search the first minute compared to how long each successive minute takes. This can help determine how much there is to gain by parallelizing the search.
