      When the elapsed time is significantly larger than the main thread CPU time, it indicates a lot of time was spent waiting for I/O (input/output to disk) to complete. In these situations, you could achieve far better performance by running this simulation on a system with more RAM, or by using a faster hard drive configuration (for example, consider using faster spinning hard drives, multiple hard drives in a RAID0 configuration, or solid state drives).
