Worried About Swap - MISSING?

[EGO-II.1]

I have been using Fedora 25 happily now since it's release, but when I 
happened to run /etc/fstab while trying to "find" a USB stick I noticed 
this output:

  Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/fedora-root /                       ext4 defaults        1 1
UUID=a305554f-e0cf-47dc-8f9b-b8799276038d /boot ext4    defaults        1 2
/dev/mapper/fedora-home /home                   ext4 defaults        1 2
/dev/mapper/fedora-swap swap                    swap defaults        0 0
/etc/fstab (END)

My question is: Should I be worried that it's NOT showing a SWAP 
partition? And could thi be why this laptop which has sufficient RAM is 
kind of slow? And finally how would I go about adding a swap partition 
from the command line (as opposed to a GUI...trying to learn how to do 
more in the magical "Little Black Box"!) Any help offered would be 
greatly appreciated.


Thanks In Advance

Looks to me like you have a swap partition.  use # swapon -s to see a summary of info
about it.

It doesn't show a mount point because swaps are not mountable.

If you follow /dev/mapper/fedora-swap it will eventually lead you to a 
physical location.

cat /proc/meminfo will show, among other things, how much swap you have 
and how much of it is available.

Things that manipulate swap:   /sbin/{mkswap,swapon,swapoff}

Use the `mount` command or `cat /proc/mounts`

It shows a swap partition.  `cat /proc/swaps` to see what swap is in
effect, and `free -m` to see how it is being used.

No.  Without swap, the computer would be fast, much faster than if it
uses its swap, until it ran out of memory.  If your computer is swapping,
that would make it slow.  `

What release? AFAIK F25 has not been released yet. Discussion should
stay on the Fedora Test list until it has actually been released.

Also, you could use:

top

in the command line to watch the activity of swap and memory live.

My apologies, I
didn't realize that it hadn't been released already. 
Seems I've been using a beta? I'll just clam up about the touchpad until 
its officially unleashed on the masses! LoL!


Cheers!
