RE: [ActiveDir] Active Directory Performance for 64-bit Versions of Windows Server 2003

Umm.  Did you read the whitepaper this thread is talking about? From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nicolas Blank Sent: Sunday, April 02, 2006 3:21 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Active Directory Performance for 64-bit Versions of Windows Server 2003 Haven’t “lurked” on the list for a while, so apologies if I’m asking the answered, however: Bearing in mind the non-goals of the paper, i.e. ·      Finding a precise database size at which the 64-bit version becomes more advantageous than the 32-bit version. ·      Finding a precise amount of RAM to optimize caching the database.   Any prescriptive guidance on these bearing in mind that most of our DIT’s contain more than just user info? Also, how do multiple processors affect 64 bit DC performance? What about DC specific settings in 64bit environments, do these change at all, since larger cache configurations are assumed – the thinking is here that you wouldn’t bother with 64 bit dc’s without the extra memory…   From: Grillenmeier, Guido [mailto:[EMAIL PROTECTED]] Sent: 02 April 2006 09:58 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Active Directory Performance for 64-bit Versions of Windows Server 2003   although nothing official, we've done testing HP internally and were quite comfortable using a single well-sized 64-bit DC (well-sized meaning our whole DIT cached in memory) serving one of our sites with approx. 4 Exchange Mbx. servers (I believe all dual-proc) with a total of 20.000 mailboxes.  It worked like a charm.   /Guido   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Sonntag, 2.
