    I too am issues system wide, including Firefox, Chrome and downloading updates from the AppStore.

     

    Try disabling iCloud in the Control Panel, this brought my speedtest.net results back in line with my work PC.

     

    Not the best solution for me considering I am a heavy iCloud user, but it at least brought my system back to where it is usable...

         I had the same problem as others here in that after installing Mountain Lion the performance of my 2011 21.5" Imac really slowed down, especially in Safari.  Pages that used to load in 2 seconds now took 15-30 seconds or didn't load at all.  After trying different steps on my own, I finally called Apple support this morning.  These are the steps the Apple tech had me perform:

    1.  In Safari, go to prefences and remove Cookies, then Develop menu, and empty caches.

    2.  Shut down the machine and unplug it for one full minute.  This resets  the SMC.

    3.  Start up in safe mode (hold shift key after hitting power button until you see the apple icon on screen) then go to Utilities folder in Applications and open Disk Utility.  Select Mac HD on left, then Verify Disk.  When Verify Disk is completed,  click on Verify Permissions.  After completing this step, if any permission problems are listed, click on Repair Permissions.

    4.  Shut down the computer, and start up while holding 4 keys at the same time; Option, Command, P, and R.  Hold these keys down until you hear the computer chime twice.  This step resets the PRAM.

        After doing these steps, my computer now functions as fast as it did in Lion.  Apple support is really great!  I hope these steps help you too.  Good luck!

    I had already emptied the cache and the cookies. Since then Safari was a little better but far away from perfect. Now, after following the steps inicated by jrtan24, Safari is now 100%!

    Thank you!

    OrangeKid, check "Show Develop menu in menu bar" in Andvaced tab of safari preferences.

    I know this wont help everyone but I had those exact sypmtoms after upgrade i.e. 45 secs to load a page and solved it simply by resetting my router from the router access page in safari (not by switching it on and off at the mains)

    In case someone is still looking - this was fixed by the latest apple update.

    they call it reliablity update - but really it removes the buggy javascript library and now everything is running super fast.

    hope this helps

    Nicolas, it's an update to fix java files which are causing many computers to run slowly, not a complete system update.   Like you, I didn't know there was an update until I read clarkboy2's response above.  If you go to "Apps" under the Apple menu, then click on updates at the top of the window, you should see the update.  It only takes about 30 seconds to load.

    Hi, I had similar symptoms with Safari 6.  Peformance issues, hang-ups and drop-outs on page loads, etc.  Turns out I had the AdBlock and 1Password extentions installed.  When I uninstalled AdBlock, Safari performance was noticeably better.  So now, I'm much faster but annoyed by ads!  The 1Password extention for now seems like it is not a suspect.

    You know I've wondered about the quality of Apple's offerings after Steve Job's passing wondering if short cuts or exceptions ere being tollerated.  Mountain Lion is one HUGE dissapointment with me for it seems that EVERYTHING either slows down or works inconsistantly anymore.   As one user said it reminds me of Apples VISTA.  Seemed before Apple always had great beta testing and the products they submitted were ready for prime time day one.  Mountain Lion is not one of those products and although I have a 17" MacBook Pro with the 2.8Ghz Core i7 chip my computer is so slow that I've thought about returning to a Windows machine in order to enjoy some speed once again.  I'm not there yet but this is embarassing and really is detrimental to my view of Apple these days.

    Well, there are bugs in every software release.  This has happened before and will happen again with every company.  Apple has always had it's share of incidental failures, I mean the harwarde and software issues when Jobs was around was just as problematic, if not more so.  If you think Apple software and hardware was absoultely ready for prime time on day one, I'm not sure what system you were using.  I think now there is a straw man excuse everytime something isn't 100% perfect - oh it's because Jobs died!  For all intents and purposes, Jobs was out of the picture at Apple for over a year before his passing.
