Turn off disk performance monitors

Turn off disk performance monitors  Views: 118,630 | 11/14/2002 | Written by: Tweak Import | Print 

In Windows 2000 and XP Performance Monitor disk counters for physical disks are turned on by default, disk counters for logical disks are turned off by default.

You can disable all disk monitoring by running this command

DISKPERF -N

To turn it on again run this command

DISKPERF -YD


all DISKPERF switches:
   -Y  Sets the system to start all disk performance counters
       when you restart the computer.
   -YD Enables the disk performance counters for physical drives when you
       restart the computer.
   -YV Enables the disk performance counters for logical drives
       or storage volumes when you restart the computer.
   -N  Sets the system to disable all disk performance counters when you
       restart the computer.
   -ND Disables the disk performance counters for physical drives.
   -NV Disables the disk performance counters for logical drives.

    This will not work on XP, as disk performance monitors are permanently enabled. Not sure about Windows 2000. On earlier versions it should work perfectly though.

    I ran the Diskperf /? and this doesn't do anything on XP (read the last line of the command prompt output): C:Documents and SettingsChristian>diskperf /? DISKPERF [-Y[D|V] | -N[D|V]] [\computername] -Y Sets the system to start all disk performance counters when the system is restarted. -YD Enables the disk performance counters for physical drives. when the system is restarted. -YV Enables the disk performance counters for logical drives or storage volumes when the system is restarted. -N Sets the system to disable all disk performance counters when the system is restarted. -ND Disables the disk performance counters for physical drives. -NV Disables the disk performance counters for logical drives. \computername Is the name of the computer you want to see or set disk performance counter use. The computer must be a Windows 2000 system. NOTE: Disk performance counters are permanently enabled on systems beyond Windows 2000.

    This will work with Windows 2000 and Windows NT but performance gains will be minimal. It will do nothing on Windows XP and later. Disk performance counters are permanently on for these systems. Larry Miller, Microsoft MCSA

    I work today still with Xp Pro and I use the diskperf -N... this and other register changes did the pc work noet as it should be... I can't go anymore into the safe mode... So I found this information and set the diskperf -YD... This on administrator and normal start windows. Note... For close the cmd... not alt - f4 works but simply exit! Why I write this answer... IT WORKS ON WIN XP!

    I was the autor from last reaction on this site... Topic diskperf! I forget to explain... That the safe mode woks again by enable the diskperf... I think to mistake to make the diskperf settings also in administrator Windows... But because I don't know what to do.. the settings in administrator Windows or in normal windows... I use the diskperf -YD... Now is everything ok... Note... The reason of this act? Old pc... 1.7 cpu and 512 memory... So I search much possibilitys to make the system fast... Again... Diskperf works on WINDOWS XP Proffessional.
