Once upon a time the computer was so slow that for getting an output we had to wait for hours. But now a days it produces output almost instantly! still we are not satisfied with it’s speed, we become angry if it delays 1 or 2 seconds to give the result. This ends with a conclusion that nothing can satisfy us. OK now lets have some tricks to speed up your machine performance which is running ubuntu as its operating system.
If you are using multi boot system, Ubuntu displays a GRUB boot loader menu for 10 seconds before the actual operating system boot starts. Even if you don’t use multi boot system still ubuntu displays this GRUB boot loader menu for 3 seconds. This GRUB menu display time can be controlled in your ubuntu grub file. So to modify this setting type the following command in the terminal.
sudo gedit /etc/default/grub
And press enter. Once the grub file opens find GRUB_TIMEOUT in that file and change the value to 0 (if you do not use multiboot). The number actually represent the time in seconds. So set the time to zero(0) means the grub menu will not display now onwards and it will load ubuntu by default. Still if you want to access the grub menu, you can access the boot menu by continuously pressing the arrow keys or Escape key while your computer is booting.
After changing the time save the file and type the following command to apply the change.
Startup applications are those applications which starts loading with your operating system. So it tremendously reduces your system performance by increasing the operating system loading time. So try to reduce the applications in startup.
Click on Dash Home or press Winkey -> Type Startup -> click on Startup Applications -> select the application from the “Startup Applications Preferences” window -> click Remove.
According to me the few applications are heavy and this applications are not required. Following are some of the applications, and you can uninstall them for better performance.
sudo apt-get remove software-center
sudo apt-get autoremove software-center
sudo apt-get install synaptic
sudo apt-get autoremove ubuntuone-client python-ubuntuone-control-panel
sudo apt-get remove totem
sudo apt-get remove rhythmbox
sudo apt-get autoremove
sudo apt-get update
sudo apt-get install smplayer
Swapping reference to moving data or information from RAM to the hard disk swap area. I have noticed most of the time that ubuntu does not even use half of the RAM. It uses swap though you have free RAM available. Using to much swap slows down your system performance. You can control the swapping preference in a configuration file.
To change the swapping value type the following command:
sudo sysctl vm.swappiness=10 (temporary, persist till next reboot)
to change the swapping value permanently open the file sysctl.conf by typing the following command
sudo gksu gedit /etc/sysctl.conf
after opening the file find vm.swappiness or type your own if not exists
and then save the file.
If you often use libre office then disable the Java environment in your libre office to increase the performance of your libre office. Though some features will automatically be disabled which are not that much important.
To disable Java in libre office:
click on Tool in libre office ->Options -> LibreOffice -> Advance -> uncheck “Use a Java runtime environment” -> click OK
Clean Cashes and un-used dependencies by typing the following command in your terminal
sudo apt-get autoremove
sudo apt-get autoclean
Run these two command after installing or uninstallng any applications, it removes all unnecessary dependencies of partially installed application and its dependencies.
I will be happy if the tutorial helps you
