To /3GB or not to /3GB that is the question
Most say they see no difference.
SBS engineers have said don't do it.
A KB says no....but there are enough vague ones out there that say ...yes do it...
What am I talking about?
The /3GB switch. I have 4 gigs of RAM and have never messed with that setting. I have folks that have messed with it and see no impact.
So... start the debate.... do you? Don't you? Do you see a difference? And note the two sections of the KB below... I'd say that's a “don't do it“.... wouldn't you?
If you are having memory issues...check out the blog links on allocated memory alerts.
*Note* For Exchange Server computers which are at the same time Active
Directory Domain Controllers or Global Catalog servers we do also not
recommend setting the /3GB switch in boot.ini. We recommend having
dedicated Active Directory Domain Controllers or Global Catalog servers.
Note You do not have to use the /3GB switch on Microsoft Windows Small
Business Server 2003-based computers. We do not recommend that you use
the /3GB switch parameter in the Boot.ini file for Exchange Server
computers that are also Active Directory domain controllers or global
