Where did my memory go?

After some months using Windows Server 2008 x64 as a desktop, and after installing some of these, one thing's for sure: memory usage starts low, but doubles with ease.

So I've decided to measure memory usage on a new laptop I've just received, a Dell Latitude D830. Here's what I got:

Description	mem	mem delta
Installed Windows Server 2008 x64	392	392
Stopped some useless services	372	-20
Installed HyperV	445	73
Stopped HyperV services	415	-30
Installed Windows File & Search services	432	17
Installed Office 2007	465	33
Removed  Groove Utility on startup	446	-19
Installed Visual Studio 2008	496	50
Stopped SQL Server services	470	-26
Installed NVIDEA driver	525	55
Stopped NVIDEA utilities on startup	500	-25
Installed wireless service	525	25
Installed Desktop service	555	30
Started Themes service	555	0
Activated Aero	615	60
Installed driver bluetooth	615	0
Installed and starting  Messenger 8.5	700	85
driver wireless	730	30
Starting Outlook	830	100
Starting FeedDemon	880	50

Update: Mobile Center: +12MB

 

Like always, we start with an acceptable 392 MB usage, but we always end up getting near 900MB with great ease. Just to get to a minimal usage. And I didn't throw a web browser here...

Here's the same list ordered dependently by memory usage:

Description	mem delta
Installed Windows Server 2008 x64	392
Starting Outlook	100
Installed and starting  Messenger 8.5	85
Installed HyperV	73
Activated Aero	60
Installed NVIDEA driver	55
Installed Visual Studio 2008	50
Starting FeedDemon	50
Installed Office 2007	33
Installed Desktop service	30
driver wireless	30
Installed wireless service	25
Installed Windows File & Search services	17
Started Themes service	0
Installed driver bluetooth	0
Removed  Groove Utility on startup	-19
Stopped some useless services	-20
Stopped NVIDEA utilities on startup	-25
Stopped SQL Server services	-26
Stopped HyperV services	-30

 

Outlook and messenger on top, as expected. Interesting how Aero doesn't suck that much memory. And yes, search services mem can probably depend on how much you're indexing.

Throw in some Firefox and IE, some Visio, Excel and Word  docs, a Visual Studio debug session and your favorite Virtual Machine, and you'll quickly asking for the other 2GB of RAM you didn't get (yet). Oh well, nothing new here, just glad to know where did my memory go :)
