Unless you use their Turbocap card or a Shark Appliance, timestamps are not accurate in some cases.

You can look at the field "dns.time" in the DNS response and you can create an I/O graph as follows:

  • Use "Advanced" units on the Y-axis.
  • Fill in the filter "dns.time" and calc: "AVG(*)" with again "dns.time"
  • Enable the graph by clicking on "Graph 1"

(similarly you can add "MAX(*)" and "MIN(*)" graphs)
