Hi there,
The important measure is the available which in your case is 5772MB. So nearly 75% of your memory is available.
Only if your available memory is full, only then the system will start writing to the swap.
Also very important side note, I would really not advisable having such a huge swap file, as if the system starts storing so much information in swap it could really slow things down.
Regards, Bobby
