I recently installed Service Pack 1 for Windows Server 2008. Since that time, network performance has been awful. Both Windows 7 and Mac Snow Leopard clients have seen miserable speeds when trying to read or write to the server.
This is the exact update:
Windows Server 2008 R2 Service Pack 1 x64 Edition (KB976932)
It's a very simple file server setup. No Domain or Active Directory. Essentially just shared folders. It's Windows Web Server that I'm running.
Are there any settings I can tweak? Should I roll back the update (doesn't seem wise)?
I've turned off the Power Management for the Network Adapter. That may help. If it doesn't have to be powered on at the start of a request, it should speed things up. Or so I would assume.
