![]() The number of vCPU = CPU cores * threads per coreĬheck CPU cores with lscpu command in Linux.The number of CPU cores = sockets * Core per socket.There are 2 threads per core in most of the current CPU architecture. This is different than the number of CPU cores, as it measures the number of tasks that can be processed at the same time. In Linux, threads per core is a way of measuring the number of threads that can be processed simultaneously on a single CPU core. However, it is important to note that not all processors support hyper threading. This can be useful if you are trying to optimize your system for performance, as it can increase the number of tasks that can be processed simultaneously. It allows a single CPU core to process multiple tasks at the same time by creating virtual cores. Hyper threading is a feature that was first introduced in Intel processors. Understanding CPU cores and hyper threading in Linux This can result in a significant increase in performance.īut the number of CPU cores is not the same as the number of processors. This means that, if you have multiple CPU cores, your system can process multiple tasks at the same time. In Linux, a CPU core is essentially a processor. When you are trying to optimize your system for performance, it is important to understand the concept of CPU cores. The following commands can be used to check the number of CPU cores in Linux. Let’s get started! Methods to get number of CPU cores in Linux This is useful information to have if you are trying to optimize your system for performance.Įach method has its own advantages and disadvantages, so be sure to read through all of them before choosing the one that is best for you. In this blog post, we will discuss 3 different ways to check the number of cpu cores in Linux.
