I do not understand what you mean by poor performance.
How is your hard drive partitioned. Using the terminal post the output of the command:
sudo fdisk -l

Sir michaelk : I have partitioned the DISK when I was installing UBUNTU 12.04 on my system. I have not done any thing with 100 GB partition only I have done is given the 80 GB to root and 120 GB to SWAP AREA. and I installed the UBUNTU 12.04 on the root /. As I am NEW on LINUX and Don't now the Partition Scheme. First of all I would like that plzz any one tell me what is the standard partition Policy on LINUX UBUNTU 12.04. and how should a partition can done .. and finally the ans of my thread que...

The default is two partitions / and swap. Since you are new to linux the default is ok. There are many ways to partition the drive with linux and without knowing how much RAM, what applications you run or how you use your computer it is difficult to say what is best or how much swap space you really need. I would set the swap space to equal the amount of RAM.

okk michaelk O_o :: I have 2 GB RAM .. So my swap area should be 2GB. Now As I have given the swap area 120 GB how can I reduce that upto 2 GB and utilize remaining Part without formatting my System once again ... Is there any Utility which provide such a solution??

I have listen that we can change the partition on Linux after installing it. But in my case it is not working.

You'll be able to resize your partitions with that.
