vmstat是Virtual Meomory Statistics（虚拟内存统计）的缩写，可对操作系统的虚拟内存、进程、CPU活动进行监视。它是对系统的整体情况进行统计，不足之处是无法对某个进程进行深入分析。
vmstat命令用来获得UNIX系统有关进程、虚存、页面交换空间及CPU活动的信息。这些信息反映了系统的负载情况。vmstat首次运行时显示自系统启动开始的各项统计信息，之后运行vmstat将显示自上次运行该命令以后的统计信息。用户可以通过指定统计的次数和时间来获得所需的统计信息。

4.>bindprocessor -q
The available processors are:  0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

5.总结：
1）lsdev -Cc processor 可以查看到虚拟处理器（Virtual CPU）是8个；
2）bindprocessor -q 可以看到逻辑处理器（Logical CPU）是16个；
3）vmstat 可以看到lcpu是逻辑CPU的个数是16个，ent是物理CPU的个数是4个；
4）prtconf 可以看到内存的大小是8G；
