X-BeenThere: freebsd-performance@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Performance/tuning List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 17 Mar 2008 09:24:50 -0000 I have just upgraded 5 of my machines to V7 from 6.3 and then realized that all the machines has a high CPU usage. Almost all of them using 80%-90% CPU with more than 8000 connections. Using previous 6.3, it only uses 40-50% CPU with the same kind of connections. Using top -S, I can see that swi5: +, PID 17 process is using 30% of CPU time. What is this process? All the machines are Intel C2D 6300 except one which is a AMD 4000+. Is this normal for V7? How do I downgrade to 6.3 if this V7 killing the CPU? TIA
