单CPU中系统和TMM共用CPU0,但在图形界面里独立显示两个利用率

Updated: 3/11/08 10:23 AM On single CPU systems, although the Linux operating system and TMM share CPU0, the CPU usage graph in the Configuration utility displays CPU0 usage and TMM CPU usage separately. CPU0 represents the active CPU usage of all user and system processes, excluding the Traffic Management Microkernal (TMM) process. TMM CPU Usage represents the active CPU usage of the TMM process only….

为啥TOP里看TMM占用CPU很高

In previous versions of BIG-IP, the majority of the traffic was processed by the system kernel. Beginning in version 9.0, the Traffic Management Microkernel (TMM) processes traffic. This change causes UNIX command utilities, such as top and ps, to inaccurately report CPU utilization at approximately 80% utilization for single processor systems and 99% on dual processor systems….
