I have a powermac intel something with 8 cores

Now safari is running like it is in treacle with everything taking an age to open lke 5 minutes to open a web page

Chrome running at the same time is opening stuff **** near instantly

I've removed click to flash which i was running and it made zero difference

So any ideas?

    From your Safari menu bar click Safari / Reset Safari. Select the top 7 buttons. Click Reset.

    Back to the menu bar click Safari / Preferences then select the Extensions tab. If you have any installed, turn that off, relaunch Safari. See if that makes a difference.

    Could be third party unsupported Safari plugins, troubleshooting help for that here. "Safari runs slowly"

    If Safari is getting very slow:

    (Presumably you regularly empty your Safari cache by deleting the following file:


    and clear your History)

    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.

    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 as is described here:


    You can cancel DNS pre-fetching by going to Terminal and typing:

    defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false

    You have to restart Safari for it to take effect.

    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.

    For this and other reasons Apple switched their websites to HTML in January 2011:

    A couple real basic ideas:

    1. Have you had your ISP check your signal, modem and/or router?
    2. Have you unplugged everything (Mac, Modem and/'or router) for five minutes and
    then restart everything again? That often gets rid of a lot of spider webs . . .
