Teveel geheim voorgeheugen van het Uitzicht van Vensters, slechte ting? Goed, blijkbaar ja, door Caching Bovenmatig schrijf I/O en Bovenmatige Caching Gelezen I/o. Zoals u waarschijnlijk onderhand het weet, wordt het geheime voorgeheugen aangesloten aan het opvoeren van de prestaties van gegevens toegang totprocessen die trage opslagmiddelen richten. In een ideaal scenario, zouden de gegevens of de codepagina's volledig gevestigd worden binnen het systeemgeheugen. De snelheid waarbij het gegeven, in de fysieke RAM wordt betreden, overschrijdt veruit dat van gelijkaardige processen die een harde schijf, door ongeveer 1 miljoen keer impliceren. Maar wegens de gewoonlijk beperkte hoeveelheid RAM, zal het werkende systeem systeemgeheim voorgeheugen moeten behandelen. (meer…)

Hoewel het in termen van de opties vrijwel gehandicapt is verstrekt het eigenlijk aan de gebruiker in vergelijking met Vensters XP, is het nut van harde schijfdefragmentation in het Uitzicht van Vensters een evolutie van het equivalent van het voorganger werkende systeem. Maar de verhogingen komen hoofdzakelijk onder de kap van het hulpmiddel. In deze context, was de daadwerkelijke defragmentationmotor omhoog gestemd, evenals het beheer van het fragmentatieproces.

„Door gebrek, de defragmentsdossiers van het defraghulpmiddel slechts kleiner dan 64 megabytes (MB). Daarom worden de dossiers groter dan 64 MB niet onnodig bewogen. In earlier versions of Windows operating systems, if the defrag engine was in the middle of a large move request, it could take lots of time to cancel defragmentation. In Windows Vista, the defrag engine processes input and output requests in smaller portions. Therefore, you can avoid situations where the defrag engine is busy with processing large move requests when you cancel a defragmentation session”, Microsoft explained. (more…)

When troubleshooting any version of Windows, learning what applications and processes are loading on startup is a critical step. To this end, the old and faithful MSCONFIG application is a great help, and it’s definitely present in Windows Vista too. Just go Start, Run, MSCONFIG and you’re there.

However times change, and while MSCONFIG is a very useful little utility, there are better options available. Enter Autoruns. Developed by Mark Russinovich and Bryce Cogswell of Winternals (now Sysinternals and owned by Microsoft), Autoruns is a fantastic freeware app which does a full scan of your system and presents you with a total rundown of everything that happens on system startup and system logon.

Every once in a while you notice that your hard drive is working extra hard for what seems like no reason. A background process has taken your hard drive hostage, forcing it to thrash loudly as it struggles to keep up with the high rate of reads and writes. Your computer responds slowly as the process overloads the physical limitations of your drive. What are you to do?

The solution is simple, although a little tricky at times: identify and stop the process that is killing your drive. There are two methods and tools that you can use to identify the process. (more…)

Previously (here and here), I've written about isolating shared services so that they run in their own process, with a specific focus on the Windows Update Automatic Updates Service (wuauserv) that typically runs in the NETSVCS SVCHOST.EXE instance. One thing that can be done once this is accomplished is to lower the priority of the process so that when the service winds up consuming 100% of the CPU, the system doesn't become unresponsive.

Since we're dealing with a service, setting the priority of such a SVCHOST.EXE process can become problematic - the service may already be running, or, because it is a service, it is not started as non-service processes are, so one is not able to use START / [LOW NORMAL HIGH REALTIME ABOVENORMAL BELOWNORMAL] to impose a priority when the process starts. One can use a utility like Task Manager or Process Explorer to set the priority of a process on an ad hoc basis, but when the service restarts or the system reboots one has to remember to set the priority again.

Though not an ideal solution the following scripts (VBS using WMI, and PowerShell) can be used to set the
