If you have available disk space, you can typically improve performance when needed by adding a swap file. To create a swap file, do the following:
1. dd if=/dev/zero of=/path/to/my/swapfile bs=1024 count=1048576 (1024 * 1024kb = 1 GB)
2. mkswap /path/to/my/swapfile
3. swapon /path/to/my/swapfile
4. To make your swap file accessible across reboots, update your /etc/fstab to add the following line:
/path/to/swapfile swap swap defaults 0 0
5. To confirm your swap space is now available, run the following command:
free -m
