Actually I am not storing too much stuff in it since there is plenty of free memory. That was the point of my earlier posts asking why swap when there is plenty of free memory. 

Correct me if I am wrong, but I believe behavior is unused files in /dev/shm use swap space? I want to make it so it does not do that since it slows the system down 
and since there is plenty of available free memory.
