Things to do After installing Xubuntu 14.04 LTS
With the installation of Xubuntu I've been pleasantly surprised, long time since not installed
When we need to write some command in Xubuntu, we will from Terminal Emulator commands to enter in Terminal Emulator Color are:
Open Terminal:
Home> Accessories> Terminal Emulator
If we want the Terminal Emulator icon on the desktop, on the launcher press right mouse button and select appear:
Add to Desktop
Having put the commands that we find used, we will leave Terminal Emulator with the command:
exit

Before upgrading we will check that all repositories are enabled
Repositories are deposits which are stored and maintained applications and installation packages the following tabs: ----- Software Xubuntu Software and updates We find the following official repositories and maintained by the community that should always be activated ( v ): free software and open maintained by Canonical (main) free software and open community maintained (universe) proprietary drivers for devices (restricted) Software restricted by copyright or legal issues (multiverse) source Code (No need to activate this box) Download from: here we have to choose the download server (personally I always choose the main server) ----- Other Software
CD-ROM with Xubuntu 14.04 LTS ... not activate Partners Canonical Software packaged by Canonical for its members (proprietary software. No free) (Sun Java JRE, Acroread ...), although there are free applications that supplement (OpenJDK , pdf viewer ...) and we can keep it off if we will not use. partners Canonical (source Code) software packaged by Canonical for its members (no need to check this box) Independent Powered by outside software developers (or third) Independent (source Code) Powered by outside software developers (No need to check this box) by pressing the add button, it opens a window where we can introduce the full line of APT repository you want to add as the source software the APT line includes the type, location and components of a repository for example: deb http://archive.ubuntu.com/ubuntu main trusty other options we can leave and come home in the event that additional Drivers need we go to the tab:
additional drivers
Select the driver you want or need and press the button:
apply changes
Additional Drivers may be proprietary (owners), open or proprietary code tested advise using open source
Note: To create Live System. It is recommended not to have installed the drivers owners of video cards because if we distribute it to a machine with another card, these drivers may not be valid. Then we hit:

Change RAM use swappiness
Change RAM use swappiness
The SWAP memory used by the computer when RAM becomes scarce. The kernel is configured by default to work with servers with large amount of work and limited RAM. We can change the percentage of swap memory to use so to hurry the RAM usage before you start using the swap (swap). swappiness: . This is the use of swap memory in relation to the ram If you have lots of RAM is advisable to use it therefore to do the following changes: We consult swappiness the initial configuration (default 60%) with:
sudo cat / proc / sys / vm / swappiness
If the value is 60, it must change, and if it goes 10 already have (no need to do anything else). We wrote (the change is temporary basis)
sudo sysctl -w vm.swappiness = 10
We open some applications, if the result is satisfactory, keep the permanence of the setting. To save the settings, enter the file with
sudo nano /etc/sysctl.conf
In the last line we write (down with the arrow keys)
vm.swappiness = 10
Where we can change the "10" for the optimal value you want (testing to see which is the best performance). Save the changes with:
Control + or
Press Enter Close to:

Change RAM cache use pressure
Change RAM cache use pressure
The kernel is configured by default to work with servers with large amount of work and limited RAM. On a desktop system is quite common actions like opening files, directories, searches and similar cache pressure: cache pressure is similar to swappiness in swappiness memory sWAP uses the computer when RAM becomes scarce. cache pressure controls how aggressively swaps kernel to its cache, but only for file systems. the cache is largely responsible for the storage of virtual data , so it can be retrieved when needed. it is faster for the system to extract data from RAM that the hard disk cache pressure default is 100, ie 100% on performance in managing files the disc. Putting cache pressure to 50, reduces by 50% the use of cache on your hard disk to use directly in RAM This is recommended for computers that are not to be used as servers. we can change the percentage of cache pressure to use, so use the RAM usage before starting to use the file management on the hard disk. This is the use of swap memory in relation to the ram. If you have lots of RAM is recommended use therefore we must make the following changes: we consult cache_pressure the initial configuration (default 100%) with:
sudo cat / proc / sys / vm / vfs_cache_pressure
If the value is 100, must change, and if it goes 50 already have (no need to do anything else). We wrote (the change is temporary basis)
sudo sysctl -w vm.vfs_cache_pressure = 50
We open some applications, we look for files, we copy and paste files, open PDF documents, open games and play as example . 0ad (game strategy) if the result is satisfactory, keep the permanence of the configuration To save the configuration, entered the file with
sudo nano /etc/sysctl.conf
In the last line we write (down with the arrow keys)
vm.vfs_cache_pressure = 50
Where we can change the "50" for the optimal value you want (testing to see which is the best performance). Save the changes with:
Control + or
Press Enter Close to:

Preload function preload more or less corresponds to the function prefetch Windows. Preload automatically scans applications when they are executed, so that the next time you run load libraries needed before prompted by the application. In Terminal emulator write

Thereafter, the system will not boot faster, but the application load will be faster.

Prelink Any executable that makes heavy use of shared libraries can benefit from Prelinking. Prelinking resolves addresses shared library beforehand reducing the number of relocations. Prelink is also useful in the context of security and we can say prelink to load libraries in random directions until they pass next to prelink. This is useful because libraries not loaded on fixed addresses on all systems. We can install prelink with the following command:
