Its definition however is confusing because it captures the time where there is no copying because there is a pause between when new wave of map outputs is available. > current bw is definded as (bytes copied so far) / (total time in the copy phase so far) > It would be more useful > 1) to measure bandwidth of a single copy call. > 2) display aggregated bw as long as there is at least one fetcher is in the copy call. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
