How to view server parameters in Linux

I. CPU size <br/> [root @ IDC ~] # More/proc/cpuinfo <br/> you can see the details or: <br/> [root @ IDC ~] # Cat/proc/cpuinfo | grep "model name" & CAT/proc/cpuinfo | grep "physical ID" <br/> model name: Intel (r) Xeon (TM) CPU 2.80 GHz model name: Intel (r) Xeon (TM) CPU 2.80 GHz <br/> model name: Intel (r) Xeon (TM) CPU 2.80 GHz model name: intel (r) Xeon (TM) CPU 2.80 GHz <br/> physical ID: 0 physical ID: 0 physical ID: 3 physical ID: 3 <br/> [root @ IDC ~] # <Br/> note: in Linux, you can view the details of each CPU in/proc/cpuinfo. However, for dual-core CPUs, two CPUs are displayed in cpuinfo. It is often mistaken for two single-core CPUs. <Br/> physical processor ID should be used to distinguish between single-core and dual-core. Physical processor ID can be found in cpuinfo or dmesg. <br/> if there is Ht in flags, it indicates that the number of physical CPUs can be determined by hyper-Threading Technology. You can view the physical id value. If the value is the same, the preceding value can be seen on the same physical CPU, <br/> This machine has two dual-core CPUs with IDs of 0 and 3 and 2.8 GB respectively. <Br/> 2.
