Muchos, muchos usuarios, pero tu servidor está esperando 🕙 su conexión no tan buena para enviar sus requests.

Y luego esperar 🕙 nuevamente a que los responses retornen.

Esta "espera" 🕙 se mide en microsegundos, pero aún así, sumándolo todo, es mucha espera al final.

Por eso tiene mucho sentido usar código asíncrono ⏸🔀⏯ para las APIs web.
