Windows 10: System and compressed memory taking between 30-60% cpu

Ok i thought i had sorted this problem, but it seems it has come back with a vengence and run out of ideas, so i bow to your superior knowledge

System and compressed memory gobbling up CPU with lots of free memory. WTH?

I've read that "system and compressed memory" writes idle pages to memory (compressed) instead of to disk..
when memory is short.

What I'm seeing is that I have 60% free memory and yet "system and compressed memory" is running constantly and taking up 15 - 30% CPU usage.

To me, there is something wrong here. What kind of design is it that gobbles up CPU when there's plenty of memory available??????

There needs to be an option to revert to the "old way". MY Surface Pro 3 fan is coming on a lot more lately and the system often gets sluggish, yet I haven't changed my usage patterns.

"System and compressed memory" takes up all the CPU

I just assembled my new gaming rig,

and I have some issues regarding cpu usage.

On idle it can swing between 30%-100% and it is insane.

I can see in the task manager that it is mainly "Local system" and "System and compressed memory"

that takes up 10%-90% of the cpu power.

The CPU is an i5-6600K which has about a 15% tuning boost.

Hi, I'll just post my notes on this issue for you to work through to see if there's anything that helps. This is most of what's been found on the forum, and some solutions some have found to their particular problem. You can find a number of threads here using the search box above:
"system and compressed memory"
System and compressed memory.doc
System and compressed memory- solutions.doc

I did look at your etl's, but there were only basic graphs on the left?

 

ahh ok sorry, thought i'd followed the guide on what to upload, my mistake
but, from your 'solutions.doc' i did a roll back from april nvidia graphics, and post boot seems to have settled down, will continue to monitor in coming week and see how it goes, might even update them back to the 'suspect driver' and see if it returns, but atm its back to running 0.5-1.5% which im happy with.
so far so good so thanks *Smile

 

Good, it can be an awkward one - some find the CPU usage problem recurs.

As you've installed an older driver, you need to stop Win10 updating it again.

aye already done that, the thing that annoyed me, is im actually a long experienced pc builder, and i know from reading about that this is M$ new version of 'file paging' but for life of me i tried many things, even went through at one point and did a complete clean install.
Ive even removed , modified and restated my overclock, in hope but annoyed i was *sarc
But will wait for NVidia to release a new set of drivers and then just hopefully skipping the 'suspect' one might get me out of this , but time will tell see if it returns this week *Smile
I will leave this open for this week, and should it not return will mark it as solved but just wanna time tell it

 

As a new feature to Win 10, I guess in the myriad mix of possible combinations, there are bound to be quirks and conflicts at this level.

What worries me is the relative flimsiness at the user GUI level many experience with Cortana/start menu/taskbar suddenly not responding.. then there's the sheer difficulty of changing language (multiple settings) and then finding Cortana's not working and searching Settings -> 'Search results aren't quite ready yet...' etc etc etc

Not to mention the broken nature of the LHS of the start menu when used with larger menus inherited from previous editions...
Even at this superficial level MS can't get it right..

 

To be honest first thing i do on any win10 installs is install "Classic start menu" as i find it gives me the solid functionality of win7 with the extras that win10 have.
I am a fan of win10, but as you stated their are too many hidden problems, to much 'tell us what your doing, where your doing it, and how your doing it' But once you disabled a lot of this ive had relatively few problems, and as for cortana why, oh why would i need that on a pc lol.
If i want to search for something a certain Mr Google helps me out there

 

Agree, likewise I use Classic Shell, and largely treat Win 10 as a desktop OS without the apps. Cortana is a rather confused sort of thing.

But I had to tweak the appearance- originally all title bars were the same off-white- no borders- couldn't tell what overlapped what.
Aeroglass, registry tweak to add coloured background (off-white is hard on the eyes) and Qttabbar for explorer and control panel customisation...Win 7 icons..
