abnormal load time

Recently upgraded the WPT server and agents. Observed that on using the API from a script , the tests show a longer load time than the private instances (which are directly submitted from WebPageTest UI on the server).
Any inputs on this

It has to come down to a different set of options when using the UI vs the API because the UI goes through the API to submit tests. Some basic things to check:

  • Same test location?
  • Same browser?
  • Same Connectivity?
  • Test configured to wait until onload or fully loaded?
