Win Server 2003 SP2 - SQL2k5 Performance ImprovementsI have read that there will be SQL Server 2005 performance improvements in
SP2 for Windows 2003. Does anyone know the specifics on what will be improved? Thanks Hi
Just wondering where this was mentioned? The upgrade from windows 2000 to windows 2003 is advantagous because of the improvements in the underlying file hadling by the OS (I can't remember any quoted percentages but it was a very significant one!), and from http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.mspx it seems that additional work may have been done in this area, so speculatively that could be one reason amongst others!

A Where did you read this?
Why would a Windows 2003 service pack address SQL Server performance? Maybe you meant/misread SQL Server 2005 SP2?

In other words, DB2 or Oracle running on the same server might benefit in the same or similar ways. I will ask my contacts, but it is doubtful any non-NDA information will be repeated here... A From the horse's mouth:
"the change is in winsock API and it is more perceivable on SQL workloads running with > 8 CPUs + multiple NICs. It will not be noticeable/measurable on other configurations." Keep your eyes peeled because it may require more than just Windows Server 2003 Service Pack 2 on its own to have an impact anyway. A
