also have a look at preload. its an old article already, but the way the tool works, sounds like a logical speed improvement for me.

Preload is considered to be read-ahead daemon application as it analyzes the applications which user runs, and on the basis of this analysis it predicts which applications user can run next time and launches these applications in RAM. Its daemon keeps running in background all the time and saves the required information about the applications you are running so that it may load them quickly next time.

Open the terminal and run the following command to install preload: sudo apt-get install preload

Now to start preload run the following command in terminal:
sudo /etc/init.d/preload start

It will be installed instantly. Now it will run in the background and will keep track of the applciations you run.  To stop it simple run following command in terminal.
sudo /etc/init.d/preload stop

The configuration file for Preload is kept in /etc/preload.conf and the default values should be fine for most people. But if you want to tweak the operation of Preload, an explanation of the options is available in the configuration file.

 

android users, install kde-connect, its an awesome tool, shows you nearly everything what you get on your mobile phone.

KDE desktop has long been favored by many Linux geeks because it has every element to fulfill their appetite: customizable every bit of it, aesthetically pleasing desktop effects, openness to adopting new technologies such as semantic desktop, etc. Beyond all these bells and whistles, the KDE desktop community constantly tries to advance the state of the art of the desktop, experimenting with wild new ideas.

One such effort is so-called KDE Connect, which is a brainchild of Albert Vaca, as part of his Google Summer of Code 2013. The objective of KDE Connect is to seamlessly connect all sorts of devices to KDE desktop, so they can talk to each other. KDE Connect currently supports Android device and WiFi network based sharing, but support for diverse device profiles and network backends are planned for the future.

In this tutorial, I will demonstrate how to integrate Android into KDE Linux desktop by using KDE Connect. The (growing) feature set of KDE Connect is as follows.

  • Show Android battery status on KDE.
  • Share clipboard between Android and KDE.
  • Remote control music/video playback on KDE from Android.
  • Show Android notification in KDE, and keep them in sync.
  • Pause music/video playback during a phone call.
  • Send and receive simple ping messages between Android and KDE.
  • Exchange files, URLs or plain text between Android and KDE.
  • Show call and SMS notifications on KDE.

KDE Connect has two components: KDE desktop component (kde-connect) and device components (e.g., Android app). Currently, for KDE Connect to work, the desktop computer and an Android device need to be on the same local network (via WiFi). Android app relies on UDP broadcast to advertise its presence to the desktop over the local network. Once paired, Android app communicates with the desktop via a public-key based encrypted channel.

In the following, I will go over how to install and set up KDE Connect on both KDE desktop and Android device.

Install kde-connect on KDE Desktop

Kubuntu or Debian KDE

On Kubuntu, kde-connect is included in the base repositories starting from 13.10. So simply using apt-get will do the installation on Kubuntu 13.10 or higher.

$ sudo apt-get install kdeconnect-kde qt5-default qdbus-qt5

To install kde-connect on Kubuntu 13.04 or earlier, you can build it from the source as follows. You can use the same building procedure on Debian KDE.

$ sudo apt-get install build-essential cmake kdebase-workspace-dev libqjson-dev git libqca2-dev
$ git clone git://anongit.kde.org/kdeconnect-kde
$ cd kdeconnect-kde
$ cmake -DCMAKE_INSTALL_PREFIX=/usr ./
$ make
$ sudo make install

Fedora KDE Spin

Installation instruction for Fedora KDE edition is as follows.

$ sudo yum groupinstall "Development Tools"
$ sudo yum install gcc-c++ kdelibs-devel cmake qjson-devel qca2-devel git
$ git clone git://anongit.kde.org/kdeconnect-kde
$ cd kdeconnect-kde
$ cmake -DCMAKE_INSTALL_PREFIX=/usr ./
$ make
$ sudo make install
Configure kde-connect on KDE Desktop

The first step after installing kde-connect is to run the following command as a non-root user, which will activate kde-connect on the user's KDE desktop.

$ qdbus org.kde.kded /kded loadModule kdeconnect

If successful, the above command should return "true".

Now go ahead and rebuild system configuration cache as follows.

$ kbuildsycoca4 -noincremental

At this point, you should find KDE Connect menu under "Systems Settings" (which will remain empty until you pair any Android device).

I have made a little website where i have put all these steps in a table format for better reading and copy & paste.
also there is some additional info on it and whenever i do an update it will be on the website from now on as that seems more usefull than this thread format to me.


to have a look just click on tux

hope it is usefull for some :)
