Safari has recently and suddenly become painfully slow to load pages. Across the board.

 

No recent O/S upgrades. Other apps are the same speed as usual.

 

What can this mean? What steps can I take to remedy it?


iMac, Mac OS X (10.7.2)

    Hi...

     

    Several things to try...

     

    From your Safari menu bar click Safari > Empty Cache. Quit, relaunch Safari to test. If that helped, empty the Cache more often, such as after every Safari session.

     

    If that didn't help, back to the menu bar click Safari / Reset Safari. Select the top 5 buttons, click Reset. See if that helped.

     

    Most folks running Lion are having better luck with Safari by disabling the Lion "resume" feature...

     

    Open System Preferences > General

     

    Deselect:  Restore windows when quitting and re-opening apps

    Please read this whole message before doing anything.

     

    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

     

    Step 1

     

    The purpose of this step is to determine whether the problem is localized to your user account.

     

    Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.

     

    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

     

    Test while logged in as Guest. Same problem(s)?

     

    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

     

    Note: If you’ve activated FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.

     

    Step 2

     

    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.

     

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:

     

    • Be sure your Mac is shut down.
    • Press the power button.
    • Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    • Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

     

    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.

     

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Test while in safe mode. Same problem(s)?

     

    After testing, reboot as usual (i.e., not in safe mode.) Post the results of steps 1 and 2.

    Power-Cycle the router, and make sure you didn't leave uTorrent running

    Thanks for the helpful suggestions!

     

    The Guest test was good. Safari for Guest is lightning fast.

     

    The Safe Mode test ... Safari seems "a bit" faster, but not much.

     

    By the way, it took quite a long time to Reset Safari, first 5 boxes checked. By the way, yes the browser start up (eg with three tabs) IS slow. But so is each subsequent page load. So it does not seem to be a matter of the automatic site restore...

     

    As for the router, I've reset it recently, so it definitely has been cycled.

     

    Any additional thoughts?

    Hi ...

     

    Try this... 

     

    Go to ~/Library/Caches/com.apple.Safari/Cache.db

     

    Move the Cache.db file from the com.apple.Safari folder to the Trash.

     

    Restart your Mac, try Safari.

     

     

    That seems to do a more thorough job of emptying the cache from the Safari menu bar.

    Are any Safari extensions installed? If so, disable them and test.

     

    Select Help Installed Plug-ins from the Safari menu bar. Besides the following, what plugins are listed?

     

    iPhotoPhotocast

    Java Applet Plug-in

    QuickTime Plug-in

    Shockwave Flash

    WebKit built-in PDF

    Carolyn, removing ~/Library/Caches/com.apple.Safari/Cache.db seemed(!) to help. I thought the browser was faster at first. But things seem to be pretty much as slow as ever.

  • 8. Re: safari recently slow
    tahm77 Level 1 Level 1 (0 points)

    Linc, these are my plug-ins:

     

    Citrix online plug-in

    DivX Plus Web Player

    DivX VOD Helper Plug-in

    Flip4Mac Windows Media Plugin

    Google Earth Plug-in

    iPhotoPhotocast

    Java Applet Plug-in

    QuickTime Plug-in 7.7.1

    RealPlayer Plugin.plugin

    SharePoint Browser Plug-in

    Shockwave Flash

    Silverlight Plug-In

    WebEx General Plugin Container

    WebEx64 General Plugin Container

    WebKit built-in PDF

     

    I don't know what all of these are for - eg webkit - but I wouldn't mind deleting some that I probably don't use often, eg silverlight, webex, sharepoint...

    By the way, my bank page is VERY slow, and it doesn't seem to be just page reloads, so that might mean the Java it uses is running slow...

    Quit Safari. Uninstall all plugins except the ones listed in my previous message. They may be in either of the following two folders, which you can access by copying the lines below into the Finder's Go to Folder dialog:

     

    /Library/Internet Plug-Ins

    ~/Library/Internet Plug-Ins

     

    Test. If the issue is resolved, you can consider reinstalling the plugins one at a time, testing after each one, until you find the one that causes the slowdown.

  • 11. Re: safari recently slow

    I hesitate to remove the plugins, because they are standard across all user accounts, and both the other user accounts load pages quickly, with the same plugins. It has to be something associated with the user profile, no?

  • 12. Re: safari recently slow
    tahm77 Level 1 Level 1 (0 points)

    Just installed the latest Safari upgrade. Pages are loading more quickly now. Will monitor for a couple of days.

  • 13. Re: safari recently slow

    No more issues since the upgrade. Thanks for all the help and ideas.
