How do you measure RAM usage?

This is normal, in a LINUX system usually you see low free memory size with command 'free'. After some use you can see increased number of buffer; it is not a lost memory, just allocated and will be reused when needed.

Better to use 'df -h' command and look for tmpfs available space mounted on / before and after.
