Tuning Swappiness to speed up your Ubuntu!
If you have been running Linux systems for some time and you have used applications like 'top' to see what's going on in your machine, then you've probably wondered: Where has all my memory gone? You should know that the largest place it is being used in is the disk cache, as the cached memory is free and it can be replaced anytime if a newly started application needs that memory. Linux systems are made like this to use so much memory for disk cache because the RAM is wasted if it is not used and if something needs the same data again, then there is a very good chance to be in the cache memory.
Open a terminal (Applications -> Accessories -> Terminal) and paste the following code:
sudo gedit /etc/sysctl.conf
Now add the following line at the end of this file:
vm.swappiness=10
The number at the end of this line can be between 0 and 100. At 100 the Linux kernel will prefer to find inactive pages and swap them out, while value 0 gives something close to the old behavior where applications that wanted memory could shrink the cache to a tiny fraction of RAM. Save, close and reboot.
