Hi,
Thank you for the details!
I searched up our previous conversation, and I suggested to not use the elementor live filter to get the best possible performance – because with elementor a new page load has to be rendered to replace the existing results. That is usually slower as the simple ajax request.
To no use the elementor live filter, make sure to remove the “asp_es_1” class name from the elementor posts widget.
I also recommend decreasing the live results count to around 50 or less. The “load more” feature will take care of the rest if the user scrolls to the bottom of the list.
