To avoid [[Premature optimization]] always consider your system small until proven otherwise. ## Indicators - How many request per second (RPS) do your system have? If less than 10.000 you probably have low traffic system - How many concurrent users do your system have in peak usage period? if less than 1.000 you probably low traffic small system ## Benefits - You don't need to spend energy on compute optimizing - You can use [[Rich Domain Model]]s without worrying about the cost of loading them because you don't load them very frequent nor many of them
