How to increase your PC speed through swap memory ??

How to increase your PC speed through swap memory ??

Specially in UBUNTU :

Here i described some of step that all are helpful to you to create swap memory and of course speed up your PC.

Check for Swap Space

swapon -s

An empty list (for first time if there is no any already created swap):
Filename    Type  Size Used Priority

Create and Enable the Swap File

Now it’s time to create the swap file itself using the dd command :
sudo dd if=/dev/zero of=/swapfile bs=1024 count=512k

“of=/swapfile” designates the file’s name. In this case the name is swapfile. 

Subsequently we are going to prepare the swap file by creating a linux swap area:
sudo mkswap /swapfile

The results display something like:
Setting up swapspace version 1, size = 262140 KiB
no label, UUID=103c4545-5fc5-47f3-a8b3-dfbdb64fd7eb

Finish up by activating the swap file:
sudo swapon /swapfile

You will then be able to see the new swap file when you view the swap summary.
swapon -s
Filename    Type  Size Used Priority
/swapfile                               file  262140 0 -1

This file will last on the virtual private server until the machine reboots. 
You can ensure that the swap is permanent by adding it to the fstab file.

Open up the file:
sudo nano /etc/fstab

Paste in the following line:
 /swapfile       none    swap    sw      0       0
