How to find out which processes are using swap space in Linux?

Question

Under Linux, how do I find out which process is using the swap space more?

Answer 1

The top command also contains a field to display the number of page faults for a process. The process with maximum page faults would be the process which is swapping most. For long running daemons it might be that they incur large number of page faults at the beginning and the number does not increase later on. So we need to observe whether the page faults is increasing.
