Le temps moyen d'exécution est de 3,1 millisecondes, et 99 % des réponses ont été données en moins de 9 millisecondes.

On a une amélioration des performances de près de 10 % pour une simple Servlet !

On peut facilement interpréter cette amélioration. Les performances accrues sont probablement liées au fait que le système d'exploitation ne doit pas _switcher_ entre l'exécution de 200 _Threads_ en paralèlle dans le cas de Tomcat 11, ce qui occasionne donc plus de temps disponible, et donc des meilleurs temps de réponse.

Les temps de réponse sont autour de 50 millisecondes, pour un débit d'un peu moins de 8 000 requêtes par seconde, et 99 % des requêtes obtiennent une réponse en moins de 53 millisecondes !
