There is nothing that says you absolutely need a swap partition.
You could eliminate your entire swap partition altogether effectively 
removing the possibility of swapping.
Just use the "swapon" and "swapoff" commands.

vmstat is your friend...try "vmstat 1" to see an ongoing status of cpu, 
memory usage, paging, etc.  "free -m" also shows you how much swap is 
being used.
