Windows 10 a \u00e9t\u00e9 l'un des tous premiers syst\u00e8mes d'exploitation \u00e0 b\u00e9n\u00e9ficier d'un patch contre les failles de s\u00e9curit\u00e9 Meltdown et Spectre. Et bien s\u00fbr, imm\u00e9diatement, des utilisateurs ont test\u00e9 l'impact sur les performances de ces correctifs. Pour le moment il semble que ce soit plut\u00f4t positif avec des pertes minimes voire quasi ind\u00e9tectables sur les performances d'applications qu'utilisent Mr et Mme Tout-Le-Monde et de jeux vid\u00e9o.

A quel point le patch de s\u00e9curit\u00e9 Windows 10 contre Meltdown et Spectre affecte-t-il les performances ? Mercredi dans la soir\u00e9e des ing\u00e9nieurs de Google Project Zero qui traquent les failles de s\u00e9curit\u00e9 ont publi\u00e9 deux papiers scientifiques sur deux failles mat\u00e9rielles de certains processeurs. Elles touchent pratiquement tout le lineup<\/em>\u00a0Intel depuis 1995 \u00e0 nos jour, mais aussi certains processeurs AMD et SoC de smartphones et tablettes comportant certains coeurs Cortex ARM. Meltdown et Spectre permettent de faire tomber des barri\u00e8res de s\u00e9curit\u00e9 fondamentales pour les syst\u00e8mes d'exploitation.<\/p>\n
