Hi,
Average Result Processing Time is the average processing time of a query. This metric represents the average time spent processing a ResultSet from the end of the executeQuery() call to the invocation of the ResultSet's close() method (refer to the Java Agent Guide for details). It is a good indication of the amount of time spent in business logic or within the application tier.
So it can tell you the average time is spent on the query. This would tell you more of how much time it is taking the query. Keep in mind it is an average and with averages, one long time among a number a short times could lead you to skewed results in determining latency.
