Right way to identify high bandwidth user


I often find it's hard to find the real high bandwidth user. I understand the analyzer pulls data from my IOS router but could someone suggest the correct way to narrow down the high bandwidth users via the analyzer? First I thought the top connections in the Conversation window are the high bandwidth user but it does not seem to be true.

If I have a long live connection with 100MB to transfer but it uses only 10bytes/sec while the other connection has 10MB to transfer with 100KB/sec, it seems to me the first connection will show at the top in the Conversation window because over time it has more transferred (i.e., total traffic column). However, in this scenario, the second connection should be the top consumer. Could someone suggest the right way to identify true high bandwidth consumers at the moment?


Thank you.
