Using swap is not a bad thing in itself (quite the opposite in many cases).
The actual process of swapping is expensive, though, and you want to minimise that. One way to see whether you have a lot of swapping going on is to run "vmstat 1" (you don't need to be root). That will produce a new line of data every second until you stop it (^C). in the middle are two columns under the label "swap", one sub-labelled "si" and the other "so". They are respectively "swap in" (ie, read from disk back into memory) and "swap out" (the other way). If those columns hold mostly zeros, you don't have a swap problem.
