OS X Mavericks power efficient but taking too little memory

[DoctorCrap]

Most people are saying the new OS has been taking up more RAM, compared to Mountain Lion.
I face the entire opposite problem apparently.
I seem to have slow performance through everything.
I have a 4GB RAM, usually for certain tasks like browsing and playing browser games, I would occupy almost all the RAM but now after the update I am using too little resources and causes laggy animation and etc.

Is anyone facing the same problem?

No. First backup to an external drive then boot into Recovery mode and when the install first window comes up use the menu items to use 'Disk Utility'. After that install and you setup your Mac with the same username/password use /Applications/Utilities/Migration Assistant to move your Pictures/Applications/music & Documents back.

IMHO don't transfer back Network or Mail previous settings. Make those accounts manually again and doing all this will fix your problem.
