When I give the command 'free -g' and view the output, it says

             total       used       free     shared    buffers     cached
Mem:             1          1          0          0          0          0
-/+ buffers/cache:          1          0
Swap:            3          0          3

My swap is taking 3 GB of ram. And my system is running very slow because of this. Please let me know: how do I reduce swap using 3gb of my ram?

Your system has only 1 GB of RAM, which is fully used. In addition, you have 3 GB of swap, which will be userd by your system once it needs to free RAM for something.

Your system probably is slow because it has to swap files from the (fast) RAM to the (slow) hard disk where your swap resides.

No my system has 4gb ram, –  user2674154 Jan 28 at 7:49
    
I am sorry I have 2gb of ram in my system, when I tried this command 'grep MemTotal /proc/meminfo' This is the output: MemTotal: 1923456 kB –  user2674154 Jan 28 at 7:54
    
Then please update your post (using the edit function) to include the output of free -h, which provides more details. The rest of the comment remains valid. –  drc Jan 28 at 8:24
