Windows 10: WPR.exe for Windows 10 uses 2x more CPU, RAM, Disk IOPs, and Disk Space vs. Xperf

Hello Windows Support, I would like to report a likely bug that is easily reproducible in Windows Performance Recorder and I like to see it fixed as this is an important tool for determining root cause analysis for OS & Application performance issues.Problem:wpr.exe -start generalprofile -start cpu -start power -start diskio -start fileio -start minifilter uses 2x more CPU, RAM, Disk IOPS, and Disk Space then the same Providers used in Xperf.Customer workstations that already have significant CPU or Disk performance issues cannot use the above command because it is too system intensive vs.

Relation between the Three CPU/RAM/Disk Space

Hi and thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you. Please allow me to assist with your questions.

I'm assuming you are referring to the metrics being display under Performance Tab of Task Manager.

1. These usages and graphs are pertaining to current utilization level of those resources.

CPU: Based on % utilization, it means how much processing power of CPU is being consumed by one or more active processes to run instructions.

RAM: The same applies here (utlization level) and it means the more processes are running on the system, more memory is consumed. When there is insufficient hardware memory, Windows will temporarily page data to Paging pool (Paging file is stored on disk) from
memory.

Disk: This section refers to the Active Time of the disk, not free disk space. So when this is high or full, it means the disk is actively reading from and/or writing to.

In terms of relationship, when a process is launch or working, it may Read/Write to the disk, temporary store working data on the RAM and instructions runs on CPU (for example to process data).

I would suggest reading these post for further details/information:

2. Basically CPU would be used to run instructions (like process data) and such data is primarily stored on your hard disks. Depending on how the program is written, it might directly process the data in CPU from Disk hence you will see utilization levels of
both CPU and Disk to be high. If the program will read the data from Disk to Memory before processing in CPU, then you will see CPU/RAM/Disk to have higher utilization levels.

3. RAM usage is dependent on the process(es) and what kind of instructions are being executed. For example, a game requires 1 GB of memory to run, then it would take up at least 1 GB of memory, as more memory will be required to act as temporary storage. Since
CPU is used to run instructions so a game will require the CPU to process these data in RAM/Disk. Together, you can expect all of usage to be increased. If CPU is full, then you can be sure that RAM usage and Disk utilization are probably higher. However,
the ratio of increase won't always be the same.

I would also suggest reading this article to know more about the relationship between memory and CPU:

Relation between the Three CPU/RAM/Disk Space

Query Are:



1. What is the significance/working between CPU usage/RAM/Disk (Memory management) in Win-10 (64 bit)

why Disk Usage (C,D,E) shows full and practically its almost free in GB Eg: 300-400 GB

2. Please explain the significance of disk usage with CPU.

3. Please explain RAM usage or behaviour of RAM if CPU usage is Full.

Like if CPU memory is full then it tries to load on RAM or disk ...



How win-10 manage it..

 

Disk space.

Could be the Windows Update Stores files, .old files, shadow copies, etc.

Try running Windows disk clean up with the "Clean up System Files" option.

Delete files using Disk Cleanup <-- Be sure to check out the section at the bottom "To clean up all files on the computer".
