About the calculations of EQS

Hello, everyone. I just have some few questions about the EQS.
1.How fast are the calculations made by eqs?
2.What makes the calculation made by eqs slower? The number of tests it runs? The types of tests it runs? Which one is the slowest?
3.What can I do to make the calculation faster?

I followed exactly how Epic has done with their eqs set up but mine just takes longer than Epic’s example. I can’t figure out why and this is why I posted this question.
