Last year I was trying to make safari faster and I acheived this by typing in to the browser bar certain codes. I cannot seem to find the webpage that had all the codes that you change the load settings for. Does anyone know what I am talking about. It was basically changing numbers and did not have anything to do with terminal. I know about the defaults write com.apple.Safari WebKitInitialTimedLayoutDelay 0.25 change that you make in terminal. I also know about making the other thing to .0001 so dont tell me about those if you dont mind. But if you do know what I am talking about let me know where to find it again. Thanks a ton

    No idea what you did, but try this instead:

    If Safari is getting very slow:

    Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:

    If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

    (You can also enter them if you click on Advanced and then DNS)

    Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:


    If your computer is part of a network: please refer to this page: http://www.opendns.com/start/bestpractices/#yournetwork and follow the advice given.

    You could also try these codes as well: &

    If you use a Router, make sure it has the latest firmware installed.

    One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x

    This is described here:


    If Safari seems to hang for ages:

    If you have a lot of tabs open and/or a lot of pages running Flash, Safari can sometimes 'hang', requiring a restart of Safari. This can often be inconvenient, and as it is rarely Safari itself that is hanging but merely one of its plug-ins, usually Flash, there is a way using Terminal to restart the plug-ins (without restarting Safari and losing your tabs) by quitting the WebPluginHost process:

    Open the Terminal from the Utilities folder in /Applications and type

    killall -9 WebKitPluginHost

    Note that this command kills all Safari plug-ins, not just Flash. All plug-ins should start back up when you reload the page.

    Then go back to Safari and refresh any pages that were using the Flash plug-in. This also fixes the Beachball of Death. Try this whenever Safari gets slow or freezes. The latest versions of Flash 10.1 appear to have improved the situation somewhat, but haven't completed eliminated it.
