This is what you can do to increase your Ubuntu access speed and performance

1. Set swappiness to the allowed lowest value, usually the default value is 60

rumy@cbug-nest:~$ cat /proc/sys/vm/swappiness
60

2. Edit /proc/sys/vm/swappiness and change 60 to 10 (assuming RAM > 1 GB)

sudo pico /proc/sys/vm/swappiness
{change 60 to 10, save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}
cat /proc/sys/vm/swappiness
10

3. Edit /etc/sysctl.conf, and add vm.swappiness=10, vm.vfs_cache_pressure=50 to the end of file

sudo pico /etc/sysctl.conf
{move cursor to the end of file and then add this}
vm.swappiness=10
vm.vfs_cache_pressure=50

{Save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}

4. Reboot
