This wait event will not impact on user sessions. No end user has ever telephoned the help desk to complain that "the wait event such-and-such is too high". What are they complaining about? For example, is it a query that takes too long? Or a batch job that doesn't finish in time? You need to focus on the problem before trying to find a solution.
