The performance of my scripts is very slow when running on IE11. Some of my scripts run on chrome in 2-3 mins and that takes more than 25 minutes on IE. I am using Robot Framework and most of my locators are xpath. My application does not have ID locators for the elements. I tried switching to CSS for experimental purpose but that improved the performance by little margin. I understand that since IE does not have a native xpath engine, IEdriverserver uses wicked-good-xpath for parsing. This xpath library is supposed to be the fastest. Is there any other modification/enhancement I can do to improve the performance of my scripts.
