From the articles below, we know the NETWORK_IO composed by network transmission + Client application dealing with the rows.
That's suppose the NETWORK_IO is 100 seconds, so my question is how many seconds spent for network transmission , and how many seconds spent for Client application ?
As If I don't know the time spent for the two components respectively, I wouldn't know if it is a network issue Or Client application issue.
