how to check number of cores in linux

In Linux, you can view the number of physical CPUs, cores, logical CPUs, and linux. In Linux, when you view the number of physical CPUs, cores, and logical CPUs, we recommend that you enable the number of worker processes to 1 to 4 times the number

  How to learn more about CPU information in Linux systems. Of course, it is checked by Cat/proc/cpuinfo, but for example several physical cpu/several cores/several threads, these questions how to determine. After viewing, my development machine was

Check the number of physical CPUs, cores, logical CPUs, and linuxcpu in linux. I. First, we need to clarify the concept of the number of physical CPUs, the number of cores, and the number of logical CPUs. 1. Number of physical CPUs: the number of

information in the Cat/proc/cpuinfoprocessor The ID of the logical processor. ID of the processor that physical ID physically encapsulates. the ID of the core ID for each key. CPU Cores The number of cores in the same physically encapsulated

When learning Swoole, the recommended number of worker processes to open is 1-4 times the number of CPU cores. So I learned how to check the CPU core number # View the number of physical CPUs cat/proc/cpuinfo| grep "Physical ID" | Sort| uniq| wc-l#

: This article describes how to view the number of physical CPUs, cores, and logical CPUs in Linux. if you are interested in the PHP Tutorial, refer to it. When learning swoole, we recommend that you enable the number of worker processes to 1-4
