The number of CUP cores is the number of cores a CPU consists of. The more cores, the faster the running speed of the CPU and the better the performance.

How to check the number of CUP cores by Linux

1. Check the number of CPU

Cat / proc/cpuinfo | grep "physical id" | sort | uniq | wc-L2. Check the number of cores in each physical CPU

Cat / proc/cpuinfo | grep "cpu cores" | uniq | wc-L3. Check the number of threads per CPU core

Cat / proc/cpuinfo | grep "cpu cores" | uniq | wc-l\ 4. Then the number of threads supported by cpu is the number of cpu * the number of cores per cpu * the number of threads per core
