Sizing
From Sun Ray User Group Wiki
Sizing server based computing solutions is not quite as cut and dry as people wished it was. There are far too many variables from applications, concurrency, user types, network constraints, etc. The goal of this page is to get some real world numbers from Sun Ray users across the world and share them with the community.
