Trop de cachette de Windows Vista, mauvais ting ? Bien, apparent oui, par excessif caché écrivez l'entrée-sortie et l'entrée-sortie lue cachée excessive. Comme vous savez probablement à ce jour, la cachette est reliée à amplifier l'exécution des processus d'accès aux données qui visent des supports de stockage lents. Dans un scénario idéal, les données ou les pages de code seraient complètement plac dans la mémoire système. La vitesse à laquelle des données sont accédées, dans la RAM physique, excède de loin cela des processus semblables qui impliquent un disque dur, par approximativement 1 million de fois. Mais, en raison de la quantité habituellement limitée de RAM, le logiciel d'exploitation devra traiter la cachette de système. (plus…)

Windows XP contient plusieurs arrangements tweakable de mémoire dans l'enregistrement, un dont est la clef d'enregistrement de DisablePagingExecutive. Ceci commande si le logiciel d'exploitation transférera ses dossiers essentiels de conducteur et de grain à la mémoire virtuelle de `' (le dossier de page sur le disque dur). Il se transfère sur permettre ceci.

Évidemment, les parties de transfert du système à la mémoire d'entraînement dur peuvent considérablement ralentir des choses vers le bas, et il s'avère que Windows XP fait ceci périodiquement, si le système est réellement bas sur la mémoire physique (RAM).

Windows Vista “out of memory” errors are intimately connected with the way the operating system manages virtual address space. On Microsoft’s latest operating system, applications have their very own private virtual address space. You must understand that there is no correlation between the virtual address space available to a certain program and the total volume of physical memory installed on the computer. On 32-bit platforms, applications are generally limited under a 2 GB boundary as the maximum size of the virtual address space. In this context, the “out of memory” errors in Windows Vista are generated by applications that have eaten up all the virtual address space allocated to them.

“Every memory allocation, file mapping, or library that is loaded by an application consumes space in this virtual address space. When the application consumes all its virtual address space, any additional such operations fail. Although all applications should be coded to handle memory allocation failures, many applications do not recover correctly from such failures. Therefore, the programs may become unstable or stop responding after they recover from such failures”, Microsoft informed. (more…)

Just because Windows Vista is such a resource hog, the operating system features the Windows Experience Index, a rating system designed to measure the capability of the computer’s hardware configuration in order to assess the overall performance of the machine through a numeric base score. The algorithm for determining a base score ranging from 1.0 to 5.9 is directly connected with the processor, physical memory (RAM), graphics, gaming graphics and the primary hard disk. However, there are a few contexts in which the Windows Experience Index, the mechanism at the basis of the system rating will present and erroneous score for the hardware configuration.

This is a problem observed following the commercial release of the operating system back in January 2007. (more…)
