How can I observe HTTP request-response latency?

0

I'd like to see HTTP request/response latency. I tried using tcp.calculate_timestamps and tcp.time_delta, but the latter is empty. I'm using a Mac in case that matters.

/Applications/Wireshark.app/Contents/Resources/bin/tshark -b duration:3600 -o tcp.calculate_timestamps:TRUE -i en1 -f 'tcp port 80' -w capture.bin

I open the capture file in Wireshark and add a column for Delta time (conversation). Its value in all rows is empty.

I found the answer to my own question:

When I opened the capture file in Wireshark, I had already entered a display filter. I removed the display filter, and the values appeared in the Delta time (conversation) column. Then I added the display filter again.
