There's a lot of misinformation about this.  The tmpfs does _not_
"consume 50% of [your] RAM".  The maximum size of a tmpfs defaults to
50% of RAM, but it only uses space as needed.  Also, space used in tmpfs
can be pushed to swap (so if you run low on RAM, files in tmpfs will be
pushed out to swap on disk to free up RAM for programs).
