processing performance as another host. Of course, the actual situation will be much more complicated. Different Quantities of cache, processor frequency and other factors may cause performance differences. However, even if the actual performance of these factors is slightly different, the system still calculates the average load based on the number of cores of the processor. This gives us two new rules: • "How many cores is the load" rule: in multi-core processing, your system average value sh

This command has two major uses, one is to see if your machine has recently been restarted, or because of hardware, and so on, the other is to look at your CPU load.
