Great Whitepaper on MOSS Capacity Limits
Ever wonder how many documents a MOSS document library can support? Or, how many lists you can have on a site or how many columns you can have on a list? There is a new whitepaper on TechNet that I found that answers these and lots of other capacity and performance questions for MOSS. Check out "Plan for software boundaries (Office SharePoint Server)".. http://technet2.microsoft.com/Office/en-us/library/6a13cd9f-4b44-40d6-85aa-c70a8e5c34fe1033.mspx?pf=true.
