Nope for me its been fine. Safari actually got faster and I tested it using Speedometer.Anyone experiencing issues with Safari not loading websites randomly or taking a very long time to load websites? Ever since updating to 12.4, Safari has been extremely unreliable in loading websites. Some will not load and I have to try a few times, others take a long time to load or render.
When I try the websites in Google Chrome, they load instantly.
Can you try this web test?
Do it in Safari and Chrome but not at the same time.
