You’ll probably have four options, the one in brackets is currently being used by the disk specified in the previous command:
noop anticipatory deadline [cfq]
Two of these are better suited to SSD drives: noop and deadline. Using one of these in the same situation, the application will still hang but only for a few seconds instead of until the disk is free again. Not great, but much better than cfq.
sudo vi /etc/rc.local
for dev in sda sdb
do
echo deadline > "/sys/block/$dev/queue/scheduler"
echo 1 > "/sys/block/$dev/queue/iosched/fifo_batch"
done

====Fine tune SSD by using ramdisk====
Using a ramdisk instead of the SSD to store temporary files will speed things up, but will cost you a few megabytes of RAM.
Open your fstab file:
sudo vi /etc/fstab
Add this line to fstab to mount /tmp (temporary files) as tmpfs (temporary file system):
tmpfs /tmp tmpfs noatime 0 0
tmpfs /var/tmp tmpfs noatime 0 0
====Fine tune firefox====
Firefox puts its cache in your home partition. By moving this cache in RAM you can speed up Firefox and reduce disk writes. Complete the previous tweak to mount /tmp in RAM, and you can put the cache there as well.
Open about:config in Firefox. Right click in an open area and create a new string value called browser.cache.disk.parent_directory. Set the value to /tmp.
====Install eee-control====
reference: http://greg.geekmind.org/eee-control
- sudo dpkg -i eee-control_0.9.3_all-jaunty.deb
====Install Skype====
- Install qt4
- sudo dkpg -i skype-debian_2.0.0.72-1.i386.deb
