Slow loading safari pages

Safari takes forever to load on my wife's Mac. It does eventually load, then is slow to load next page. Slow loading pages started a couple of days ago. Until then the Mac was very responsive.

What would cause such drastic drop in performance? What can I do to restore mac to previous performance level?

I have similar problems, on 2 iMacs, 2GB-ram, latest OS etc. Even did complete reinstall form DVD.

What I notice is that when I let a page load until I get the "network diagnostics" page and run the diagnostics in most cases everything turns back to normal. I do not even have to reload the stalled pages, they simply reload (of course) and quick (not of course).

Maybe this helps someone?

I have followed all advice already including cleaning cache, favicons etc. Changing DNS (google, own ISP, opendns,....) some sudo + tricks but nothing seems to work except the network diagnostics.

Good luck you all

How did webkit update itself? I downloaded webkit from http://builds.nightly.webkit.org/files/trunk/mac/WebKit-SVN-r66052.dmg but unless I double click the webkit.app nothing happens. Did I misunderstood you?

Would be great if the browsers start to work again. It is a mystery. Firefox and Safari (and omniweb) behave very similar. When I access a troubles page (maps.google.com) from within FF with TOR proxy it works fine but without it stalls.

No luck so far. Browsers still very slow if not slower. Via proxies all is fine so the wireless network we use seems to work. Skype, email and all also fine, no problems. mDNSResponder is hanging/not getting data from the network. I can see it sends but it doesn't or cannot receive data. I turned on LittleSnitch for a moment to check this. Well, the mystery remains...

Hi,

I went to http://nightly.webkit.org/ and downloaded. Start up Webkit

You can use Webkit in place of Safari. Webkit is Safari...Safari is Webkit. But the side-effect for me was that Safari 5.0.1 started working properly again.
Of course there is not guarantee you will get the same result.

Under the Safari menu - there is "Check for Webkit Updates..."

you won't believe it but it seems ⚠ to work. I did do a lot of things:
- reset to the default settings in airport
- configure step by step airport and the network settings

but in the end what made a true difference was
sudo dscacheutil -flushcache

Suddenly the kartat.eniro.fi page loaded in a flash 🙂

Very likely the effectiveness will degrade over time but I will try to "sudo dscacheutil -flushcache" again and see what happens. Perhaps I write a startup script for this

Nada, or in english, nothing. It works once and a while with this "trick". The last time Safari told me "this page cannot be loaded" or something along those lines. I got the "network doctor" again let it check the nextwork, all is fine and pages reloads again.

Don't get it
