Nous ne savons peut-être même pas que nous devons être capables d'optimiser - jusqu'à ce que nous rencontrions un problème. Mais l'optimisation est importante. Les pannes sont terribles, mais les performances lentes sont coûteuses, ennuyeuses, inutiles et également assez terribles. Il faut aussi penser au développement durable ; en général, les logiciels optimisés consomment moins d'énergie et nécessitent moins de matériel pour fonctionner. Le monde numérique a une empreinte carbone importante, mais nous pouvons la réduire en optimisant.
Mais les gens sont peut-être la raison la plus importante d'optimiser. Les applications lentes frustrent les utilisateurs et, dans le pire des cas, peuvent même les pousser - ainsi que leur entreprise - à aller ailleurs.
