Windows Web Server 2008 R2 x64 - Physical Memory always high

The physical memory on the web server is always around 95% or 3.8GB of the 4GB), even when there is little/no activity. When I look at the memory usage in Task Manager, the sum of the memory being used looks to be only about 400MB.

Any thoughts on what I am looking at here? Is this somehow normal?

i can guarantee your system is using ALOT more than 400 MB.

Here is a screenshot of the resource monitor... seems to say the same thing though. Resource Monitor

it actually says 3743 MB in use, also Don't forget that you need to check the working set, private and committed RAM as well.

Most of it is probably being used as a WEB cache to speed up the server web access.

I hope this helps !

Right.. 3.8GB or 3743 MB... still, essentially all of the memory in the machine.
I was hoping it might be web cache.
Hopefully I don't really have a problem here.. but the server seems somewhat slow for what it is actually doing. This is the only instance of Web Server that I have... maybe it manages memory differently to improve web performance?

It's MS. You want fast, go with linux.

you seriously need to add more memory.

cbmm - how do you come to that recommendation of more memory? 4GB is currently in place and I can't see where more than 400mb is actively used.

cbmmCommented:
91% or your memory is in use. you have 341MB free out of 4000MB

cbmm - I don't know if you saw the original post, but when I look at the memory usage in Task Manager, the sum of the memory being used looks to be only about 400MB. So the question I am trying to answer is who/what is using an additional 3.2GB of memory that is not reported in task manager. The box is sitting there, dormant, without CPU activity, but the memory usage is through the roof without any explanation.

w3wp.exe is using 431MB, msspeng.exe 71MB, theres 500MB with just two processes.

500MB < 3.8GB... so help me identify the missing 3.3GB

cbmmCommented:
that was adding two processes out of probably 60

if you want to add them all, use the resource monitor, go to memory and start adding.

I know you are trying to help, and I appreciate it. I guess seeing the system in front of me makes it easier to tell that the memory counts don't add up without actually doing it...  

You can see the attached screenshot that shows a new view... IIS has now gone up to almost 1GB, but notice the total memory use is by far less at 1.8GB. And the memory counts on this screen shot do add up as expected.

You can also see in the screen shot that all of the other processes sum up to less than 300MB, and these are all sorted by memory use, just like the prior screen shot, so the memory use by the other 47 processes (everything except w3wp.exe and msspeng.exe) is similar.

I think this screen shot supports the fact that the sum total of memory in use previously reported of 3.8GB couldn't have possibly been correct, or that I don't understand how the memory total is defined (which is likely the case). mem2

remember that there is "reserved memory" also. you have 2.2gigs free now, but monitor it throughout the day to try and get an average use. you may find this article useful:

The issue was related to ESX memory configurations and not the app.
