Understand Linux-based RAM and it’s cache

Linux Operating System that powered by Linux kernel have an advanced disk cache algorithm that used to store frequently access data from Hard disk.

This is to explain why some Linux server’s RAM still getting high memory usage even you upgrade your RAM.

To find out how much memory using by the Linux-based server, you may use the linux command “free” to track it. To get the detailed/actual memory usage, you may run the following command from your Linux box.

free -m

You should get some result as below,

             total       used       free     shared    buffers     cached
Mem:         15905       2879      13026          0        384        900
-/+ buffers/cache:       1593      14311
Swap:         3999          0       3999

With the result above, you may see that the used memory is 2879MB and free memory is 13026MB. However, the cached memory is 1593MB while the actual free memory will be 14311MB.
