Un changement a \u00e9t\u00e9 propos\u00e9 pour le noyau Linux, optimisant le fonctionnement du nouvel allocateur de m\u00e9moire virtuelle (swap allocator) lors des op\u00e9rations li\u00e9es \u00e0 la mise en veille (hibernate). Au cours du processus, l'un des d\u00e9veloppeurs a remarqu\u00e9 que la r\u00e9servation rapide de grandes r\u00e9gions dans la partition de swap n'\u00e9tait pas support\u00e9e lors de la mise en veille. Sur les syst\u00e8mes \u00e9quip\u00e9s de SSD lents, cela a engendr\u00e9 des probl\u00e8mes de performance pour les op\u00e9rations utilisant des blocs de 4K, entra\u00eenant un ralentissement notable de la mise en veille. <\/p>\n

Lors des tests sur un syst\u00e8me \u00e9quip\u00e9 d'un disque dur Samsung SSD 830 (SATA II, 3,0 Gbps), le patch propos\u00e9, qui ne comporte que quelques dizaines de lignes, a permis de r\u00e9duire le temps de transition en mode veille de pr\u00e8s de 10 fois \u2014 de 324 \u00e0 35 secondes. L'inclusion de ce patch dans la branche du noyau 7.0, actuellement en d\u00e9veloppement, ainsi que son backportage vers les versions 6.18, 6.19 et peut-\u00eatre d'autres branches stables prises en charge, est envisag\u00e9e.
