Windows 7: Higher Ram Usage in Svchost and Updates - way to view service ram?

Higher Ram Usage in Svchost and Updates - way to view service ram?

Ive noticed my ram usage is up more than normal, usage up 400-600MB. (Total 8gb.) This usage came about as some batch of windows updates lately. I have noticed inflated svchost processes. Currently the largest process I have is usage 194MB, and is an svchost. It had been 370MB, but I stopped the superfetch process temporarily, and it dropped over 150MB.

My running processes hardly add up to the 2.3GB being used. How can I see how much ram a service of a process uses? Process explorer and task manager dont show this.

Post a screenshot of Task Manager - Performance tab.

The total process memory usage will never equal total memory usage. Modern operating systems are far too complex for anything that simple. The memory usage of a process can vary greatly for a wide variety of reasons. There are situations where usage of 370 MB by an instance of svchost.exe would be a reasonable value.

It is not practical to do this. It would require advanced tools and very detailed inside information that has never been published by Microsoft.

Thank you for the reply.

Id like to mention I have seen svchost use almost 800MB when using the windows update service aswell.

Currently the system is running on a consistent 18% (normal, 1.5GB, total commit 1/15, 19%) ram usage now, once I see any increasing usage I will update this with information from the performance tab.

So it seems overtime (8 hours uptime) it went from 19% to 28% in use, with the same programs running. I noticed a svchost with the following services running has 390MB in ram.

Wlansvc
UxSms
TrkWKs
SysMain
PcaSvc
Netman
hidserv
audioendpointbuilder

I started and stopped svchost and it returned to 150MB in use, 25% ram use. Although that does not explain where the other 5-6% goes.

Physical Memory
total 8140
cached 5934
available 6041
free 155

Kernel Memory
paged 390
nonpaged 116

System
Handles 17800 (approx)
Threads 758
processes 62
commit GB 1/15

Hopefully this information helps.

If you would post a snap shot as requested by LMiller7 requested in post # 2 would be very helpful.

I willl try and get an image uploaded. Is there anything extra besides the graphs that an image will provide to solving this? The information I have above was all from that performance tab.

Thank you.

The numbers in post #4 seem quite reasonable. It appears usage is about 2 GB which on a 8 GB system is not unusual or cause for concern. Adding up the memory usage column in Task Manager is rarely useful and will never equal total usage. There are very significant users of memory that are not processes, not all of which are shown in Task Manager. It is not possible to fully account for all memory usage with Task Manager.

There are multiple legitimate reasons why the instance of svchost.exe is as high as it is.

Even now on 59 processes with tge same programs open I have 31% usage. It was at 33, but svchost had went up to almost 400MB, with svchost causing it again.

So there seems to be something that the average task manager cant see that is increasing the ram usage, but I dont know what.

Pictures from your system like these might help.
Chasing a few MB of ram usage can be very fruitless.

You know what I think. I think, you should stop looking at Task Manager, stop looking at Memory Usage. We are no longer in the olden days where ever megabyte was precious and must be guarded and saved. You have some 8192 megabytes to play around with now. You do not need to sit there and micromanage it.


However, if you truly need to manage your RAM and keep as little of it in use as possible this method will work the best.

Turn off your computer, open the case, look for the RAM modules, take all of them out, put them in a box, store in a cool dry place. Next take a 1 GB stick of RAM put it into an empty slot, close the machine backup and power on. Windows will no longer touch your precious memory.

And yes, I am very serious.
