Ubuntu 14.04 runs slow on AMD A4 - 4Gb Ram

Recently I bought laptop of ASUS with configuration

Even after installing LUbuntu, I didn't see much increase in speed.

Currently installed softwares - LAMP stack - Eclipse IDE

Is there anything I am missing out to perform configuration to achieve maximum performance out of a Quad Core Processor

In order to make your system faster, you could try the following:

Install the proprietary AMD driver, so the APU speed can be regulated.
Open Software & Updates, go to Additional drivers and select fglrx.
Install the packages preload and prelink. These take certain actions to make the system faster.
Execute sudo apt-get install prelink preload in a terminal.
Reduce Swap usage. The default swappiness value is 60, which may be too high.
Open the file /etc/sysctl.conf and set the swappiness parameter:sudo nano /etc/sysctl.conf in a terminal. New line at the end: vm.swappiness = 10, then another linebreak, save with Ctrl+O.
Enable boot profiling. The next reboot may take a bit longer, but the following should be faster.
Open /etc/default/grub and append profile to the line that says quiet splash:
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash profile"
```
If you don't want your boot menu to appear (if it even does), set GRUB_TIMEOUT=0
Save, exit and run sudo update-grub.

If you apply these changes, your computer should get faster after a reboot.
