shm/shmfs is the filesystem used by used for temporary storage as tmpfs .
/dev/shm is the physicaly shared memory from RAM which is used to speed up execution in Linux/unix . i.e. if a programme is having a portion of memory that can be shared to another programme if permitted .

We can increase our /dev/shm if we have enough RAM , for better performance .
