Is there any easy/automated way to debug if any of the pages are generating multiple image request(s.t calls). Its quite difficult to validate page by page as we have over 900+ pages on our website.
Try Adobe Auditor Tool powered by Observe Point. It is free for Experience Cloud Customers and can audit your site up to 500 Pages.
If you can add filters and run it twice or thrice, you can cover your site.
