NUMCPUVPS question

Simple question, but possibly an answer to our performance problems: What would be the possible effects of having NUMCPUVPS equal the number of physical CPUs in a database server?? I contend that this would cause the other oninit processes (the server side of the connected clients) to hang ready waiting for a cpu to become available. Since the CPU VPs are context-switching between other VPs without relinquishing control, then the client pieces would get very little process time and the cpu load could build up and user response time would suffer. Am I close, off base, or what?? Thanks in advance, Doug Agnew dagnew@charlottepipe.com
