. Therefore, if we look at linux, as long as we don't need swap space for swap, we don't have to worry about too little memory. If we often use a lot of swap, you may have to consider adding physical memory. This is also the Standard for linux to check whether the memory is sufficient. View the real number of CPU cores in Linux Many people know that you can view detailed cpu information by directly typing cat/proc/cpuinfo. The information is divided into processor 0-n.
