taux de transfert en ab apache de référence

Question

Je suis l'analyse comparative d'une application simple helloworld écrit dans mon cadre contre le one écrit en SpringBoot.

Le journal ab pour la version SpringBoot:

luog~$ ab -n 100000 -c 20 http://localhost:8080/hello?name=rythm

Comme on peut le voir les transactions par seconde sont à peu près les mêmes. Cependant, le taux de transfert est très différent. La version SpringBoot a dépassé 4.5Kb/s, alors que la version Act n'a que 2.7Kb/s.

Je me demande

1. Pourquoi le temps de réponse est à peu près le même alors que le taux de transfert est si différent?

2. Comment améliorer le taux de transfert? J'utilise en tant que ma couche de réseau, devrait-il y avoir quelque chose que je peux faire pour syntoniser le ressac? Here est mon code qui crée la couche réseau undertow

Answer 1

Le nombre de demandes traitées est le même, mais les réponses sont différentes, à la fois dans le contenu et les en-têtes HTTP. D'où la différence dans le trafic, aussi.
