Hi Yongsheng, the only sure way to get it down is "reboot". Another way mybe to unmount/mount all filesystems (which does not work for "/" :-)
But there is no need to worry about "cached". It will go away automatically if an application wants the memory. Oh - you could write an application that mallocs lots of memory (as much as you have). This will push away the "cache". On exit, the application memory is freed. But as I said, everything is fine.
