Server 2008 R2 - Trimming Running Processes

post #1 of 3
Thread Starter 
I have Server 2008 R2 Standard installed in a VM on a XenServer box. It's doing very lowkey stuff, mostly me tinkering with AD and getting a feel for the server architecture. It is also a full time WSUS server for my home network (3-4 machine, plus any repairs I do for side work). But that's pretty much it - nothing intensive by any stretch of the imagination.

I have 3GB of RAM given to the VM, but it is always at a minimum at 1.5GB used - which seems a tad bit high to me for the very basic operations it is running, even for a server OS. Looking into the issue, I found that the SQL Server process (sqlservr.exe) is running and using 475MB of RAM by itself.

I'm curious as to if these needs to be running at all for any of the following roles:
  • WSUS Server
  • AD Domain Services
  • DNS Server (for AD)
  • IIS (for WSUS)
  • File Server (for WSUS)

Nothing stands out to me as obviously depending on SQL server for functionality (aside from maybe AD-DS, but I'm fairly new to AD so I'm not sure).

Is it safe to terminate this process and free up that extra 0.5GB of RAM or will something explode without it?

Not too big a deal.

Remember "Free" memory is really a wasted resource. The only time you should worry about running out is when your page file is being very heavily utilized. What the OS does is it says "well there is this much free memory, lets use it" if you start running till 70% or more used, then the OS will start scaling back things and using the page file more. For instance, in a Citrix VM we had that was running low on RAM the Page file was up to 3.5GB (out of 4GB) and 3.0GB of RAM was used out of 3.7GB. I gave it 7GB of RAM and 8GB of Page file, and the RAM usage shot to 5 GB and page file went down to 2.2 GB.

Turn off the VM and drop the RAM to 2GB and see how much is used, I have a feeling that it should be dropped some, and there will be more paging.

Generally though, Server 2008 is pretty slim compared to Server 2003, Server 2003 was sloppy with updates, and kept lots of useless things running.

There is currently 0 paging occuring, it's all being dealt with in RAM. I'm just used to the mantra of "if it doesn't need to be running, kill it".

Also curious as to what within the server roles would have triggered SQL server
