When I suspend my computer it stores everything on RAM on hard-disk and reloads it back to RAM when I start my computer again does this data gets stored in SWAP area ? will having a 1 GB swap partition going to help lower suspend and resume time ?

Thanks.

No, a larger swap partition will not boost performance. When you suspend / hibernate, you copy the information RAM <--> Swap, so performance is dependent on the quantity of information you are working with, not the size of the swap.

Bodhi is right. More swap is mainly an advantage if you sometimes run out of memory and for whatever reason can't/haven't installed more RAM. But in this case, more RAM is better performance-wise. –  Scott Severance Dec 11 '11 at 10:26
    
Suspend[-to-RAM] does not a swap at all –  Lekensteyn Dec 11 '11 at 11:45
    
A good rule-of-thumb is to have at least as much swap as memory (for hibernate in particular). –  user8290 Dec 11 '11 at 14:57
