Safari very slow after opening a website or refreshing a page.

Using Safari 16.5 on Ventura 13.4 on an M1 MacBook Air (16GB of RAM)


Safari is painfully slow after having loaded a website or refreshing the page I'm on.


Most notably when using these forums, after opening a page or refreshing, the page will have seemingly loaded entirely. but Safari will not respond to anything but scrolling the page. Clicking does nothing. Right clicking or two-finger clicking will produce nothing most of the time or the pinwheel sometimes.


After about 10 seconds or so, the page will start working normally. Clicks work, right clicks work, etc... all works normally until the next page change or refresh.


If I click a link the opens in a new tab more than once during this time, it seems to actually buffer the clicks, and once Safari starts working again, and it will react to all the clicks, and the open the page multiple times in multiple tabs following the amount of clicks


Only seems to happen in Safari. Firefox works fine.


Any ideas? And yes, I have already cleared cookies and cache, and website data, and have restarted the Mac.


MacBook Air 13″, macOS 13.4

Hello.


You may first might want to try updating to the latest software (which is Ventura 13.4.1), then see how this performs after that. Or, since this looks like only an Apple/Safari issue, you could contact Apple Support for Safari:

Safari - Official Apple Support

You could get help from the Apple Genius Bar for extra expertise in-person with someone:

Genius Bar Reservation and Apple Support Options - Apple

Otherwise, I don’t have any other ideas.


Hope this helps.

Seems I found the cause. The Webkit process is using up a ton of CPU, which make sense with the lags in Safari. Why it's doing that, I could not say.

Top Processes Snapshot by CPU:

    Process (count) CPU (Source - Location)

    com.apple.WebKit.WebContent (19) 99.40 % (Apple)

    WindowServer 20.90 % (Apple)

    EtreCheckPro 14.90 % (Etresoft, Inc.)

    kernel_task 6.85 % (Apple)

    secd 2.24 % (Apple)

Thanks. The Mac is fully updated to macOS 13.4.1 (c) now and it still lags.


For these types of things Apple Support is not that useful. They'd probably just suggest re-installing MacOS.
