Microsoft a lanc\u00e9 un avertissement sur la d\u00e9gradation de certaines fonctions de Windows XP Service Pack 1 sous Pentium 4<\/p>\n
Selon Microsoft, sur les postes \u00e9quip\u00e9s de plusieurs processeurs Pentium 4 d’Intel, les performances chutent de mani\u00e8re significative lorsque deux processus se partagent l’information.<\/p>\n
Microsoft met en cause la fonction UnmapViewOfFile sur l’hyperthreading du Pentium 4, une probl\u00e9matique que nous avions d\u00e9j\u00e0 \u00e9voqu\u00e9 en avril, reconnue par Intel, qui l’avait d’ailleurs \u00e9voqu\u00e9 d\u00e8s f\u00e9vrier, avant le lancement du Pentium 4. <\/p>\n
Or, Intel commercialise \u00e0 l’attention des d\u00e9veloppeurs un ensemble d’applications destin\u00e9es \u00e0 leur permettre de mieux ma\u00eetriser l’hyperthreading\u2026<\/p>\n
Le dysfonctionnement de Windows XP en hyperthreading sous Pentium 4 ne devrait cependant pas g\u00eaner grand monde. Sur ce plan, Microsoft recommande d’ailleurs d’attendre la sortie du prochain service pack Windows, si vous ne rencontrez pas de \u00ab\u00a0d\u00e9gradation significative des performances\u00a0\u00bb.<\/p>\n
Chez Microsoft, o\u00f9 depuis quelques mois on anticipe les incidents et risques divers, il s’av\u00e8re que la nouvelle politique de transparence porte ses fruits\u2026<\/p>\n
