I am monitoring sites performances of our company using webpagetest.org but an issue occured with the implementation of new the new chrome version last month.
Before the implementation of the new version of chrome, most of the sites I’ve been monitoring are under the 3 seconds mark. (See sample images below).
But after the update of on Aug. 25, the page loads 2 times slower than before.
Before (WPT test result on Aug. 24):
After (WPT test result on Aug. 25):
You will notice that the API.JS takes a lot of time to execute and to trigger the next resouces.
By the way, our company is an Enterprise level and we have Bot Management enable.
I have tried to whitelist the public IP address of webpagetest but the result is still the same.
I would like to ask your thoughts regarding my issue. Or if you have any ideas on how will I approach the issue is much appreciated.
