Your website is a gigantic resource hog, and the new layout is even more "thristy". I loaded 3 Yahoo tabs, and 20 YouTube pages. I had no lag time on YouTube. Yahoo wouldn't load half of the front page and the comments hardly ever loaded. I repeated with 3 Yahoo tabs and 20 Pornhub tabs. Again, Pornhub tabs had no problems. Yahoo tabs still epically failed. I tried multiple **** sites, because they have extremely high bandwidth requirements and heck, over 60 percent of the Internet is *. I also used CPU intensive programs (not in the browser, native windows applications) running while the various websites were contained in a single browser app. I used Firefox, Chrome, Edge, Opera, Brave, Avast browser. I have repeated this on older and newer laptops. Older and newer desktop towers. I get the same result. Yahoo is a resource hungry website that is more bloated than Firefox is. My 286 with 640k ram and 10 mg hard drive was more efficient running *** MS-DOS 4.0. Either your servers are inefficently connected, are using outdated server blades, network connectivity from starting end to distant end (I did telecommunications in the Army), your NOC is grossly mismanaged or you are using a bunch of "kids" that don't understand the difference between arrays and pointers (hint, they are vastly different, real programmers understand that... arrays cannot do linked lists, pointing to the address, rather than the value of the varible). I'm sure that you have very compentent programmers. Give them the ability to stream line your website. Adding code on top of code and using "duct tape" to make them works, makes for something that will break very fast. Study the intensive bandwidth sites, and see how they do it. Pornhub is a bigger site than yours, with more users, more bandwidth, and makes for a stream lined experience. You need to do a stress test on your site. See where the bottlenecks occur, and what algorithims are causing the drastic slow down. Yahoo started as a directory for the internet that was stream lined, after buyouts after buyouts, you are left with a website that takes forever to load. Facebook is pushing out more news (false and full of hatred, but more) and you languish. Volume over user experience. That is not good business.
