Dans la base de code sur laquelle repose le noyau Linux 7.0, un ensemble de modifications a \u00e9t\u00e9 int\u00e9gr\u00e9, \u00e0 la suite de tests de stress effectu\u00e9s sur un r\u00e9seau de 100 gigabits, permettant d'augmenter la performance du traitement des paquets UDP entrants de 12 %. L'optimisation a \u00e9t\u00e9 r\u00e9alis\u00e9e par le biais de l'inlining manuel de 2 fonctions. Il est \u00e0 noter que la fonction timecounter_cyc2time() peut \u00eatre appel\u00e9e pour chaque paquet entrant, \u00e9tant donn\u00e9 que les protocoles modernes exigent la prise en compte du temps d'arriv\u00e9e du paquet. En raison de cela, sur une charge importante, le serveur<\/a> la fonction timecounter_cyc2time() peut \u00eatre appel\u00e9e plus de 100 millions de fois par seconde. <\/p>\n

Dans cette situation, les optimisations automatiques appliqu\u00e9es par le compilateur, telles que FDO (Feedback Directed Optimization), LTO (Link Time Optimization) et PGO (Profile Guided Optimization), n'ont pas pu d\u00e9tecter le segment de code chaud et l'ont ignor\u00e9, apparemment parce que les pilotes de cartes r\u00e9seau sont fournis sous forme de modules s\u00e9par\u00e9s. Cependant, le d\u00e9ploiement inline manuel de la fonction a entra\u00een\u00e9 un gain de performance significatif.
