Is it ok if I disable Windows 10 memory compression?

Stealth3si 521 27 October 27, 2016 at 06:14 PM
If I enable memory compression (via the mmagent cmdlet in powershell) I get this "error" in process explorer about a process called "memory compression" and the path reads "[a device attached to the system is not functioning.]":


When I try to access any kind of information on it via properties settings, which there is none, it says "Access Is Denied" the only info I can see is threads tab that shows "ntoskrnlGetCompressionWorkspace" error.

Anyways, if I disable memory compression via the mmagent cmdlet in powershell, I no longer get the "error" in process explorer! The image below shows that memory compression is disabled with its "False" value:


But the other features having "True" values show that superfetch/prefetch is currently enabled. Normally superfetch enables memory compression by default when superfetch is on, until I manually disabled memory compression.

Suppose Superfetch (and memory compression) was enabled before then I disabled the Superfetch service in Service Manager, well this is what the mmagent cmdlet in Powershell looks like.

With Superfetch disabled, it also disables memory compression.

Currently, I have enabled Superfetch but since I manually disabled memory compression it stayed disabled. Otherwise, memory compression would have been automatically enabled alongside the Superfetch features.

Very interesting & thanks for your detailed explanation.

I believe that that if you disable memory auto compression you will force Win10 to use the pagefile and if you do that you will fatigue your SSD unnecessarily.

I assume from the results of my investigations that you want to reduce excessive CPU utilization, is this true, and if so I wonder if Win10 will actually allow you to permanently make this change to the OS?

It seems to me that Microsoft would have a pretty good idea as to whether or not memory compression is required or even a good idea.

Have you tried a program like Process Lasso [bitsum.com] to throttle memory compression?

I am not experiencing excessive CPU utilization. So I guess I should re-enable memory compression. And since I am having no issues, there is no need to throttle memory compression? Could this mean I have bad physical ram that is producing the memory compression "error" in process explorer (when memory compression is enabled) or is my pagefile not correctly sized (because I am letting Windows manage the size)?
