Safari Sluggish on Certain Site

Other browsers render fast

[timster]

I'm trying to figure out why the web pages on a vendors web application pages come up so slowly in Safari.

We've tested this site on a bunch of computers, and pages render quickly enough in various Mac and Windows browsers.

When we test other sites, Safari "speeds back up."

I'm thinking about trying a couple things:

- Downloading Konqueror for Linux and seeing how that performas (although I'm not sure what we can learn from that)

- Asking the vendor to create valid HTML. (Their pages aren't replete with errors but they don't validate.)

Any thoughts?

Just an idea. Does the site use a lot of FORMs and do you have Safari set to Autofill "Other Forms"?

There was/is a problem not with Safari but with the system call that retrieves form values.
You can turn that option off in Preferences, or it might since have been fixed in a Software Update.

Thanks, Doc. I went ahead and turned off all forms auto-fill stuff and it didn't seem to speed it up much.

But I clicked around some more and found out it turning off JavaScript sped the site up a lot for Safari 125.11. (Unfortunately, the site relies pretty heavily on JavaScript, so this isn't actually a solution.)

I tried a couple BenchJS tests and Safari got very poor results on several of the tests, especially the Empty loop test. It seems that Safari simply executes JavaScript code slowly.

I'm not sure if there's anything to be done about that. I guess the answer is "switch browsers for better performance."

I guess the answer is "switch browsers for better performance."

Compared to Windows users, who sometimes don't even know the word "browser", Mac users always seem to have a full arsenal on hand.
