一个进程的％MEM值是否可以在最高输出中显示超过100％？这是否有可能？
不，它不能。 根据手册，它只是物理记忆，在现实生活中你不能有超过100％的记忆，你能吗？
n: %MEM -- Memory usage (RES) A task's currently used share of available physical memory. o: VIRT -- Virtual Image (kb) The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out and pages that have been mapped but not used. p: SWAP -- Swapped size (kb) Memory that is not resident but is present in a task. This is memory that has been swapped out but could include additional non-resident memory. This column is calculated by subtracting physical memory from virtual memory. q: RES -- Resident size (kb) The non-swapped physical memory a task has used.
