Description

Your question

To measure response times for a UI web application, I ran sitespeed scripts using a docker command. I am experiencing high response times compared to manually calculated response times. Can you please let me know what could be the reason for this?

The command used to run is: docker run --rm -v "$(pwd):/sitespeed.io" sitespeedio/sitespeed.io XXX.js --spa --multi --viewPort 1786x708 --maxLoadTime 180000 --video=false --plugins.remove screenshot -n 1 -b chrome

Research direction

Reproduce the reported Docker command using the referenced XXX.js script and compare its response-time results with the manual calculation. Start by reviewing how the sitespeed.io run measures timing under --spa, --multi, Chrome, and the specified viewport. Done when the discrepancy’s cause is identified and documented or corrected with evidence.
