La soci\u00e9t\u00e9 Red Hat a publi\u00e9 les r\u00e9sultats d'une \u00e9valuation des performances des canaux de communication chiffr\u00e9s organis\u00e9s \u00e0 l'aide du protocole IPsec sur du mat\u00e9riel moderne, et a \u00e9galement compar\u00e9 la bande passante d'IPsec bas\u00e9e sur les algorithmes de chiffrement authentifi\u00e9 AES-GCM et AES-SHA1. <\/p>\n

Les tests ont \u00e9t\u00e9 effectu\u00e9s sur un syst\u00e8me RHEL 9.4, sur un serveur \u00e9quip\u00e9 de deux processeurs Intel Xeon Scalable de quatri\u00e8me g\u00e9n\u00e9ration (28 c\u0153urs et 56 c\u0153urs logiques par CPU), connect\u00e9 \u00e0 un r\u00e9seau via un adaptateur r\u00e9seau Intel E810 de 100 Go. L'acc\u00e9l\u00e9ration mat\u00e9rielle IPsec, portant les op\u00e9rations sur la carte r\u00e9seau ou Intel QAT, a \u00e9t\u00e9 d\u00e9sactiv\u00e9e afin d'obtenir une repr\u00e9sentation des performances de la pile logicielle. Les param\u00e8tres du syst\u00e8me ont \u00e9t\u00e9 configur\u00e9s selon le profil \u00ab throughput-performance \u00bb, le pare-feu firewalld a \u00e9t\u00e9 d\u00e9sactiv\u00e9, et le processus iperf3, g\u00e9n\u00e9rant le trafic, ainsi que le gestionnaire d'interruptions de la carte r\u00e9seau ont \u00e9t\u00e9 li\u00e9s au premier c\u0153ur CPU (pour \u00e9viter la d\u00e9gradation des performances due \u00e0 la migration des gestionnaires d'interruptions vers des n\u0153uds NUMA non associ\u00e9s \u00e0 la carte r\u00e9seau).<\/p>\n

Lors du test monothread d'IPsec pour IPv4 et IPv6 en utilisant un seul c\u0153ur CPU pour le processus iperf3, une performance de 6 Gbit\/s pour AES-GCM et 3,75 Gbit\/s pour AES-SHA1 a \u00e9t\u00e9 constat\u00e9e, soit une diff\u00e9rence de vitesse d'environ 40% en faveur d'AES-GCM.
\nLors des tests avec plusieurs flux parall\u00e8les (chaque instance d'iperf3 \u00e9tant attach\u00e9e \u00e0 un c\u0153ur CPU distinct), la bande passante de pointe avec AES-GCM atteignait 50 Gbit\/s pour IPv4 et IPv6, d\u00e9montrant la capacit\u00e9 d'exploitation compl\u00e8te de la bande passante disponible sur un type le serveur<\/a> avec deux connexions de 25 gigabits ou une connexion de 40 gigabits sans utiliser d'acc\u00e9l\u00e9ration mat\u00e9rielle (ou la moiti\u00e9 de la bande passante d'une liaison de 100 gigabits utilis\u00e9e lors des tests).
