question about tmpfs

Hello,

I have a question about tmpfs.

On my raspberry pi I with only 256 MB RAM df looks like.

root@pi:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 15G 2.0G 13G 14% /
devtmpfs 111M 0 111M 0% /dev
tmpfs 115M 0 115M 0% /dev/shm
tmpfs 115M 13M 102M 11% /run
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 115M 0 115M 0% /sys/fs/cgroup
/dev/mmcblk0p1 56M 20M 37M 36% /boot
tmpfs 23M 0 23M 0% /run/user/33
tmpfs 23M 0 23M 0% /run/user/0

Is tmpfs "overload"?
What happens when a add a new tmpfs partition e.g for squid?

Is there a way to manipulate the size of the "default" tmpfs shown
above? In /etc/fstab I cant found anything about tmpfs.

root@pi:~# cat /etc/fstab
proc /proc proc defaults 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
# a swapfile is not a swap partition, no line here
# use dphys-swapfile swap[on|off] for that
root@pi:~#
