No vayas ha dedicar tiempo a repasar esto, he creado el PR para q lo veas, si no te cuadra simplemente rechazalo. El benchmark es poco útil en cualqueir caso, sólo re-confirma lo obvio 😉.

PD: no me pidas cambios que no los voy a aplicar 😅🤣

Estuvo muy bien la discusion. Tengo que meter cosas de RxJava con Schedulers. Buen area para mas Esgrima guena :)
