I am currently using Imperva Advanced Bot Protection. They inject an async script in the head of my page source as one technique of many to help filter out unwanted black hat bot traffic. This script loads very quickly but I am seeing it on PageSpeed Insight reports as having extremely high evaluation times which does cause consistently higher Total Blocking Times (TBT) on reports. See report screenshot below. I wish Page Speed Insights could help give me insights into why the evaluation times are so high. I know Page Speed uses network throttling and emulation which can be inconsistent so having a reason would be helpful in diagnosing. Is there a way to find out why the evaluation times are so high so I can get with Imperva technical support to have them optimize the script?
