safari on mountain lion is slow

Try shutting down your computer, check your wifi/ethernet connection, try quitting safari, and check activity monitor to see if another program is causing safari to slow down.

To check activity monitor look at the cpu %. If one program has a very high cpu %, quit it if you can.

Ok lol that's not the problem..did you do all the other things mentioned?

Same problem here. Painfully slow uploads and downloads. I need to roll back to Lion. It's not my system: Mac Pro 2010, quad processor, boot is a 240 ssd, Black caviar drives in raid. Lots of ram. I am really disappointed. Thankfully I didn't install on my laptop.

If I restart my computer I have fast internet connection but that only last for a couple of pages and I need to restart. Sometimes double clicking on the address bar helps (or maybe relieves my frustration) Activity monitor is the same as Mr. Stinky Panda.

I am a photographer so I need to upload big files all the time.

If anybody finds a solution I'd love to hear it.

Thanks forum people!

Same problem here. Just upgraded my late 2011 MacBook pro 13 and the new Safari is SSSSLLLLOOOOOWWWWWWWW! Unbelievalble! What is going on with Apple? This is very annoying and frustrating. Is there a fix for this?

I noticed the same thing at first. Did you also install the software update that pops up from the App Store? Ever since I did, and restarted my computer, things seem to be running a lot faster. Not sure if that's the reason, but worth a shot.

What update are you talking about?

Hey media_lush, I could be mistaken, but a day after I installed Mountain Lion, a notification popped up in the top right corner of my screen. It was an update via App Store for iPhoto, Aperture, and Mac OSX Mountain Lion. I installed it, it restarted my computer (was pretty fast), then my computer made a crazy loud beep noise, then restarted, and it has been better since then. I may have incorrectly seen this and it was only for those other apps, but I feel like I did see the Mountain Lion symbol as one of the items that would be updated. Hope that helps. Maybe go in the App Store and check for updates?

I think those updates were the updates for Mountain Lion compatibility which you could update on regular Lion ... which I did before I installed ML a couple of days later. I have had no updates appear in the top right corner.

Regarding slowness.

I have to say that Safari 6 is useless at handling multiple tabs.... it just grinds to a standstill! What I would do in the older version was that when things started to slow down (I had 3 windows with about 25 tabs open in each.) I would just force quit 'Safari Web Content' from the Activity Monitor (it would be around 1.8GB at the most) and whilst the windows and Safari would stay open all the tabs stopped loading/refreshing andany subsequent tab I went to would load really fast and scrolling would be smooth again.

With Safari 6 if I just opened one of my pages with tabs the Safari Web Content would hit 2GB really quickly and scrolling would practically stop working. A second window would take it to 2.7GB and Safari would grind to halt everywhere..... this time if I force quit 'Safari Web Content' all the windows would close and when I reopened they would all open in tabs again but ony the first few tabs would work okay before everything grinds to a halt again.

If I could I would like to go back to the previous version..... guess I'm going to have to look at Chrome and Firefox again which I don't like using.

I've been using Mac for decades now and Safari, too..... I can't believe that the last 2 major updates of Safari have been a bit of a total fail for me (and numerous other people judging by the posts here)

Either the people testing only open a couple of pages at a time or quality control re software is getting worse. Apple should be worried and ashamed about this!

One of the things that I really dislike about Lion is the multiple tabs reload simultaniously and spin endlessly, and there is nothing you can do stop the process.

I have been having the exact same problem. I finally installed Google Chrome which is running much faster. I never had any problems with Safari before I upgraded.

I swear this update of Safari has to be the worst one ever!!!!

*** were they thinking by getting rid of favicons....when you look at a web-page with loads of tabs open on a 27" imac it's impossinle to differentiate which tab is which without pressing your nose against the screen.... who's bright idea at Apple's was that.... some hipster dude who thinks 'grey' looks cool? I can imagine the problem might be worse on a Retina laptop. Also the difference in grey variance between an active tab and the others is practicaly non-existent so, yet again, you have to squint to see which one is open.

If anything the speed issue seems to be getting worse.... first few tabs fine.... then it's like crawling through treacle.... I have 8GB ram, - this never happened with the older Safari version....

Also some other have mentioned scrolling seems to just stop working on some pages with huge bits of white space.... I can confirm the same for me.

Did all the beta testers just open one or 2 tabs and that's it?

I could have bought myself a new Ferrari with all that I've spent on Apple over the years and have to say the last 2 Safari updates have been truly terrible.

Steve Jobs would never have accepted this version.
