Performance :: High CPU Usage - System And Compressed Memory
Feb 23, 2016
For a while I 'm having problems with locking while I surf the internet after five minutes browsing the facebook the browser begins to catch and is impossible to do anything , I noticed that this occurs when the system and compressed memory reaches 15% use the CPU when closing facebook use immediately falls to less than 1 % and the browser back to normal. I never had it before and started to happen with these recent updates.

I'm running a 64 bit Windows 10 laptop. On idle, the System process is showing a high memory usage of more than 150 MB, usually more than 200 MB. Using poolmon the pooltag SpDN showed up with a memory leak. It leads to the Intel Matrix Storage Manager driver, iaStorV.sys. How should I go about fixing the problem?

Is there any way to stop the "system and compressed memory" from happening? I am so annoyed by it's constant 90% Memory usage! I used to have only 8 GB of RAM and it would use 7GB out of the whole 8GB. I recently upgraded to 16GB and everything was fine. System and Compressed memory was only using 1-2GB but now it's skyrocketed up to using 90% memory (14GB). What the hell is this feature?

After installing Windows 10, I have consistently been getting high memory and cpu usage by both the System and Service Host: Local System processes. Usually the usage keeps rising from 1GB to sometimes 8GB. I left my comp on while I was at the gym today and came home to it prompting me with a low memory available message. This must have shut down some processes because now my pc is running at 13% memory and 2% cpu. I have searched for this issue and found similar threads, but none of the solution work for me.

Installed Win10 yesterday for free, everything went without a hitch that day. Today after rebooting and having installed new updates, I fire up World of Warcraft and after a minute of playing I get a freeze for 20 seconds, followed by an error message from Windows that WoW is causing memory issues.
I open up Task Manager and WoW is sitting at a happy ~1.5GB RAM usage, while another program called "System and Compressed Memory" is at 3.4GB RAM usage, after a minute it went back down to ~200MB, but kept spiking to 1-2GB
I read up on this process online, but only ever came up threads of people having issues about it consuming too much CPU, mine was sitting at 0-1% usage during that lockdown for that process.
The process is supposed to facilitate RAM usage, but so far it has only caused issues, and I never had any RAM issues on Win7. So, is there a way to shut this thing off?

I am having an issue with System and compressed memory constantly using at 35% CPU, resulting in the fans on my laptop running all the time and being very noisy.
I have read:
Solved Is this normal? System and compressed memory process ALWAYS at 20% cpu - Windows 10 Forums
Why is using so much CPU?? SB, th2, all updated and indexing done. : Surface
System and Compressed Memory Service High CPU Usage - Microsoft Community
and i have also tried adjusting the pagefile from system managed to Initial 2Gb and Maximum 8Gb, and disabling sleep.
But nothing i do seems to stop this usage, some people seem to report that it goes away after 30 minutes or so, or rebooting a few times seems to sort it out, but nothing seems to be working in my case!!!
I am running a genuine copy of windows 10 Pro...

When I am downloading something with utorrent the memory usage in task manager slowly creeps to 100% and makes my computer unusable and even if I shut down utorrent the memory usage does not change and I have to restart my PC. Same goes for browsing facebook or any other sites. Is there a solution to this? I really don't want to reinstall my system.

I have win 10 64-bit home on a 4th gen core -i5 laptop. I have a WDC 1T 2.5" USB3 drive. It is about half full. It used to do 60-70MB/s write speed. Since a few days ago, I noticed it has slowed down by a factor of 5-6 to 10-20MB/s. While copying large files, I watched what's going go. The System and compressed memory process was doing a lot of read and write on the disk. If the copy speed reported by the dialog is say 15MB/s, then system compressed memory process is reading 15MB/s and writing 30MB/s. It looks like this process is reading back the content written and writes back. It is consistent over reboot with several large files from 200MB to 7GB in size.
A couple of weeks ago I did a file backup. I created a 5GB virtual drive on my SSD and dumped all files to be backed up. Took only 5 minutes to copy the 5GB files to the virtual drive and copy the file to the WDC disk, at around 67MB/s, typical of this type of portable drives. While I was wondering what was going on, I tested the same files with a USB3 dock and a 2TB Seagate drive. Write speed is about 150MB/s. So I thought it was not a problem with all disks. The WDC drive has no compress to save space option, BTW. I wonder what's going on. I have AVG antivirus and I turned it off while copying and same slow 15MB/s speed.

Here is my PC configuration :
Recently I am getting notification that my memory is low, close some application to free the memory. But I wasn't running any high memory consuming programs. Then I looked into my Task manager and got this :
I am really not sure why this is taking so much memory. This Service Host: Local System continuously taking more and more memory and it moves total memory upto 80% ....
This didn't happen before I am recently facing this problem. How I can stop this so that it doesn't take this unusual memory. I checked windows update but no update is pending.

Here is my laptop specification:
- HP Pavilion g4
- Intel Core i3 2.2 GHz
- Radeon 6470m (but somehow got 7400 driver and worked) plus Intel HD 3000
- Windows 10 of course
- 2 gigs ram
- And latest drivers, checked with Uniblue's driverscanner and link on other subforum stickies.
It's high memory usage of this process, it starts with ~7mb then grows up to ~200mb on heavy use. This happen with recently windows 10 update.
What I have done is, I do a restart every time I made these changes:
- SFC /scannow
- Update driver (again)
- Turn windows 10 tips off
- Try disable Superfetch
- Malwarebytes scan
- Disabling High Definition Audio driver drops the process usage to normal 28kb, but this somehow rise again to ~100mb.

I have an HP DV4 Laptop(i5, 8GB RAM, 256GB SSD) that came with Windows 7, I recently updated to Win10. Everything seems fine except of the high CPU usage in System and Compressed memory. I narrowed it down to the Realtek Memory Card reader. I should also mention that right after the Win10 update two Realtek Memory Card Reader entries were in Device Manager with yellow exclamation icons.
I deleted them and had Windows install the drivers from Windows updates, after that everything LOOKS fine. And there's only one entry now.After a while I noticed the fan making a lot of noise, wasn't like that in Win7.Anyway, after hours of troubleshooting I eventually came back to the Realtek reader, sure enough after disabling it CPU went to normal.I have also downloaded the newest driver from realtek site.

From the moment I switch ON my desktop until switching OFF (working for 12 hours) the local system service host is always between 30% to 40% regarding CPU usage.Why? How to stop it?
This does not happen in my Microsoft Surface Pro machine. Both machines, desktop and Surface have the same software installed so it's hard to believe this CPU usage is software based.

I have a new Lenovo A740 all-in-one desktop. It has a core i7-4558U and 8GB of ram. It is also running a updated version of win 10 home. For some reason i keep getting a pop up on my screen that says "Close programs to prevent information loss, your computer is low on memory. Save your files and close google chrome". I never have a ton of intensive programs open and it always seems to pop up and tells me to close google chrome and/or Skype.
When i go into task manager and look at my processes google chrome and Skype are using a very low amount of memory. At the top of the processes there is "System and Compressed Memory" which is using 1,942.8MB of memory and my system says i am currently using 75% of total system memory. What could be causing this is how can i fix it.

I recently bought a new laptop which had Windows 8.1. After a week of having it I noticed my Disk Space near 100%. I heard this was a common problem so installed CCleaner and did disk space cleaner however none of it worked.
I then upgraded to Windows 10 as a friend said this solved the problem for him, however, since doing so either the disk space, Memory or CPU are high either one at a time or all together, regardless of what I am doing on the laptop.
The first week of having the laptop I don't believe this was a problem so I think it's something to do with an update as all games ran smoothly.
When I run a game or bring up firefox near the top is always 'system (ntoskrnl)' or a few 'service host (svchost)'. I dont believe its the games I play or firefox as like I said it was fine for the first week. It seems windows are running stuff behind the scenes.
I have done a few things that I have found on the internet but none have worked like; disable prefact and superfetch or whatever they are called. Still seeing increase in memory or disk usage whenever i load something and system or serice host are there at the top of performance or the game seems to use alot - however again the game never did this in the first week.

Task manager says my PC uses 95-100% of its memory, with the process using the most called "system" at only 200MB out of 8GB, if I set it to display how much it's using in percentages, it says 40-60%.
I'm running Windows 10 Home 64bit, on a 4770k with an MSI MPower Max Z87 Board and 8GB out of a 16GB kit of Corsair Vengeance 1600MHz CL10 RAM (I need to RMA the other 8GB, it's broken), CPU overclocked to 4.0GHz, no memory overclock.
I'm wondering whether it's a software or hardware problem, and if it's the former, how can I fix it?

I just recently installed Windows 10 on my Dell Inspiron Laptop and so far I am not impressed at all - in fact, I am very seriously debating one of two actions - re-install Windows 7 or switching to an entirely different OS.
The reason for reverting to Windows 7/switching OS are as follows:
1) Currently with an idle system (i.e. no applications running at all), an svchost process is using anywhere from 40 to 60% of my cpu. When I did a tasklist on this process the following processes are attached to this one pid: Appinfo, BITS, Browser, DsmSVC, IKEEXT, iphlpsvc, LanmanServer, lfsvc, ProfSvc, Schedule, SENS, ShellHWDetction, Themes, UserMananger, Winmgmt, wuauserv. My question is this - is it necessary for these processes to be run. If they are, then am I looking at only being able to use 50% of my processor (since this one pid is using the rest of it)?
2) For a virus scanner - I am using McAffee and under Windows 7, it took my laptop 24 hours to scan 231 GB of data. Since I switched to Windows 10 (Same hardware, same memory, etc) it now takes my virus scanner over 48 hours to scan 231 GB of data.
3) If I had not been poking around and trying to change my update settings, I would never have found out that Microsoft expects their users to update the windows of the other users (Microsoft calls it Dynamic Updates). Now this is all well and good if some one had said something since I would have loved to know about it sooner since I am on a metered service.
4) Some of the programs that comes with Windows 10, I have no use for but yet I can not un-install them (Cortana come to mind).
5) It appears that even though I have turned off "Live tiles" the tile continue to update from the net (again - it would have been nice to know since I am on a metered service).
The only option that I know of is to revert back to Windows 7 or switch to a new OS.

I'm getting a constant high disk usage without even having anything running. Here's a screenshot of my problem
And well, so far I've tried the ''deactivate 'windows search' and 'superfetch''' and it hasn't really done the trick.
Also I resetted my pc yesterday, as of now I'm running a clean install of Windows 10.
Did the ''turn off notifications from Windows'' and really nothing, I've also defrag quite some times with Defraggler and DiskDefrag and nothing.

Basically I noticed that my PC has a lot of RAM used but no program is using the RAM - see attached screenshots. Obviously it doesnt really affect me until I launch a game: eg GTA 5 which before ran happily at 60 and is now stuck on less than 1 FPS when I get into the game (even after spending like 20 minutes in lag hell to try to reduce all the settings to the lowest).
However Rainbow Six Siege runs at 120 FPS with no issues, so GTA may be an isolated incident.
(Also important to note I only have 8Gb of RAM, even though it says */16.0GB for the committed memory)

I have recently noticed a bit of a performance issue on my HP laptop running Windows 10 Home.
What happens is, if I am not doing anything on the laptop, but am not putting it to sleep (i.e. idling), it stays at a low CPU usage. However, after a while (usually about a minute?), the CPU usage rockets up, and also affects my CPU temperatures (goes up from ~35'C to ~50'C).
The processes that are the culprit, as defined by the detailed tab of Task manager, are either "svchost.exe" or "System" - the latter is described as "NT Kernel and System" and is linked to ntoskrnl.exe.
The laptop came preinstalled with Windows 10 and doesn't have many programs installed.

So up until this morning my Windows 10 desktop has been performing really well. When the machine is idle the CPU use is only in the 1-3% range.
For some reason my idle CPU use is now CONSTANTLY 30-40% (even after a reboot)! Task manager says its "Service Host: Local System (15)". If I expand this process in task manager it lists:
Why is this happening all of a sudden? I have all Windows Updates installed and I run an i7-3770 CPU.
My machine is now slow/sluggish with 30-40% being hogged by these services!
I don't have any Malware installed as I run Malwarebytes Premium and the scan comes back clean. Some goes for a full anti virus scan.

I just upgraded to TH2 from Win 10 Pro. I noticed that my disk usage is near 99% for the past 20 mins. It keeps fluctuatiing between 10 to 99. Normally my disk usage stays at 0. May be this might be Windows settling in after the upgrade? There was high disk usage the first time around when i upgraded from Win7.
