Use the Server Response Time Percentiles, Data Transfer Time Percentiles, Retransmission Delay Time Percentiles, and Network Round Trip Time Percentiles views on the Engineering page to find out what percentage of transactions are impacted by a given issue. If the network problem appears only in the 90th percentile view, the issue is confined to only the slowest transactions. If the issue appears in the 75th or 50th percentile views, the problem involves a greater portion of the transactions.
A few users might complain of slow application response while most users have normal response times. The Network Round Trip Time Percentiles view might indicate this situation with a 90th percentile line much higher than the 75th or 50th percentile lines. You can see that about 10% of the transactions have poor performance while the remaining 90% have better results. Perhaps users at remote sites or users of particular transaction types have poor experience.
If the 90th, 75th, and 50th percentile lines are close together, you can conclude that most users were seeing similar results without much variation wherever they were located and whatever transaction types they were executing.
