So you don't say how much swap you have configured?
Does the swap usage continue to grow after, say, a week?
Why do you care about your swap usage? Is is causing performance problems?

Your memory usage is likely to continue to be around 100% as Unix will use 
whatever it can get for the buffer cache and the like. Don't expect to see 
free memory any time soon unless you have seriously more RAM than you 
need.

Why?

If they are their then either they're being used or they're candidates to 
be discarded during page list scans when memory is needed.
