    System and compressed memory high disk usage


    Hi everyone. I am currently having issues trying to diagnose the system and compressed memory bug that causes slow disk operations. I am running a computer that I have built myself. i5 6600k, 16 GB of RAM, 2 SSD and 1 HDD. The slow operations only happen on the HDD. I can notice this when folders start to become slow and playing saved videos start to lag and drop frames. I can copy these videos and watch them just fine on the SSDs without any lag at all. I have tried multiple fixes such as disabling the notifications from windows and One Drive does not seem to be installed on my computer. I have also tried all of the solutions here BEST FIX: 100% Disk Usage by “System and Compressed Memory” in Windows 10 - Appuals.com I just tried the second one now so I'm not sure if that's going to work. I'm just a little worried that disabling the second one will have some kind of negative impact on my computer. I also have the same symptoms as the user suggested fix as mentioned in that link, but I am not sure how to go about changing the settings like they did.

    It is also worth noting that this hard drive is from a previous laptop that I put into my desktop. The system boots off of one of the SSDs and the HDD that is slow is side drive. I have tried repairing and checking the integrity of the system files, defragging the drive which I thought would help, but did not. None of the services I ran reported any problems including chkdsk. Lastly, I am still running on the 1511 version of Windows since I have not received the anniversary update yet. It's tough for me to analyze the problem due to the task manager reporting that the disk usage is 33% and system and compressed memory using 0.1 mb. I'm assuming it displays it like this since I have multiple hard drives. I have had a couple instances where the computer will freeze forcing me to shut it down by holding the power button. This has not happened as of late since I am starting to catch the slowing down of the computer and restart it to get it back into a fast state.

    Hi, if you search the forum for
    system and compressed memory

    you will find useful information in several threads. It may not be easy or quick to resolve. Solutions are different for different users. This was much discussed about a year ago- hardly any reports recently.

    Given that, I would suggest you manually update to the AU build from1511.

    Take due precautions, and create full disk images before you do so e.g. using Macrium Reflect (free) 0 disk images are strongly recommended here.

    Why? People sometimes find the upgrade fails and their PC is unbootable, or they experience widely reported new issues with the AU esp. on older hardware. So your disk images (which you can then use routinely as good practice) can save you.

    Could you please add your Win 10 build and Pro/Home to your specs.

    Thanks!

    Hi, thanks for the quick reply. I have done a good amount of research so far and haven't seemed to find a fix yet. I was actually just updating my specs when you replied :P Everything should be current now. I should also mention that Windows Defender and defrag is disabled as well. These issues seem to persist even when Chrome is closed. I just restarted my computer so everything is running smoothly again. It usually takes 1-2 days for it to reappear even after shutting down the computer every night.

    • Chrome

    Solved High CPU usage - System and Compressed Memory - Page 3 - Windows 10 Forums

    Its solved now.

    Just disable the desktop notification in Chrome

    [IMG]file:///C:\Users\David\AppData\Local\Temp\ksohtml\wpsABC7.tmp.jpg[/IMG]

    Now my W10 runs perfectly! With the FB tab still active.!

    First the problem: Apparently Chrome uses the video card memory instead of system memory to store the videos (and perhaps other stuff) on your feed. The problem arises when Windows System and Memory Compression tries to do its magic on the video memory (which I can only guess it's unable to do). When the video memory gets close to full the System and Memory Compression process CPU usage shoots up and stays up (apparently forever). The video memory isn't compressed and I can only guess the process keeps trying to compress it.

    That's why the test ran fine in Safe Mode. Because in safe mode display drivers aren't loaded and instead uses it's generic drivers. And that's also why when you disable WebGL everything works fine. But WebGL is awesome and very useful in many sites so I didn't want to disable it and I also didn't want to try rolling back my video drivers unless I didn't have a choice so here is a way to fix this problem. Instead of disabling WebGL altogether just disable hardware accelerated video decoding on google chrome.

    To do this you just need to launch Chrome, go the the address bar and type "chrome://flags" and then search (ctrl+F) for "#disable-accelerated-video-decode". By default this should be "off" but if you turn it "on" you disable it (you turn on "DISABLE" so that's why "on means off").
    =======================================

    I still recommend you upgrade as these reports have tailed off markedly from a year ago. Clearly there was an issue for some with Win 10, which introduced this process.

    Facebook notifications were already disabled. The slow disk operations happened even when Chrome was closed. I disabled the setting like you suggested. I just used videos as an example of how I know the hard drive is slowing down. Opening documents stored on the hard drive seems to take forever and it's not just limited to watching videos. I believe that this problem is what caused my computer to freeze up in the past. This computer is a few weeks old and had a clean install of Windows 10.

    Just saw your edit, are you suggesting that I upgrade to the anniversary edition? These problems surfaced when 1511 was pushed?

    I.e. to be specific - maybe MS has mostly fixed this.

    Will do.

    If the problem persists after updating, is there any recommended steps I should take? I am thinking about replacing my HDD with a newer one. Would this change anything? I'm not really sure if it is system and compressed memory causing the issue. It just shows up as the one with the most disk usage when I open up task manager. The most disk usage % will be 33% and doesn't reach 100 like other users are reporting, but it is very noticeable that the computer is running slowly and the only way to fix this is a system restart for some reason.

    Compressed memory refers to compressing pages of memory (RAM) so as to write less to disk at the expense of slightly higher CPU usage. It has nothing to do with your situation.

    When there is a demand on memory some pages will be written to disk if you don't have enough free RAM. Memory compression is designed to compress these parts of RAM and therefore not have to write them to disk (which is much slower) or rather not as much. Pages are written to your page file when there isn't room for them in your RAM. Unless you have consciously moved your page file to your HDD (in which case move it back to your SSD) then it will not impact your HDD at all.

    Hm this is odd then. My CPU and Memory usage when this occurs appears to be normal. Values are always under 35%. Any suggestions? I guess I'll need to head into the resource monitor and explore the processes that are running. It's hard for me to diagnose from just the task manager since everything appears as 0.1 mb usage. Right now in my paging file sections, it is set to be automatically managed by the system. C: drive shows system managed and the rest say "none" while currently allocated is 2432.

    Your page file setup sounds fine - I always leave it system managed. I don't know what your problem could be but it doesn't sound like memory compression to me.
