    Hello Linc.


    I have tested both suggestions and still Safari is very slow. Firefox and Chrome load pages super fast.

    Also noticed, as mentioned on previous post, that,, App Store and iTunes Store don't load at all. gives this message: Safari can't open the page "" because Safari can't establish a secure connection to the server "".


    Also suspected this was related to Network settings, so tried to reset all network settings ( -ethernet-wifi-bluetooth-system-default-mac-macintosh/)  but nothing changed.


    Any clues?

    Posted a new discussion because found some interesting info about Keychain Access:

    Mine stopped being slow the instant I disabled the AdBlock extension.

    Wasn't an issue before Mavericks, but seems to be now.


    Your mileage may vary.

    Hi Linc.


    For Step 1, Safari responds quickly when I sign-in as Guest.


    For Step 2, Safari responds equally slow after I boot up in Safe mode.  After a normal reboot, the Safari is still slow.


    I have a new Macbook Pro 15 with Retina.  It is 2 weeks old.


    Odd thing to note... I noticed this issue last week. But during the week, Safari is sometimes fast rendering the same site. is expecially slow compared to other sites.  But as Guest, it loads very fast.  Even this site is pretty slow.


    Any ideas?

    My problem is solved.  Although my Down bandwidth was fine, there was an issue with my Up bandwidth.  The problem went away on it's own after a few days.

    I agree. I've deleted web data and cookies, reset Safari, restarted iMac, tested internet speed and it's fast. I switched from a PC and Internet Explorer to an iMac and I get the same old BS! Why doesn't Safari tell us what is so slow: internet, website, or computer? There's no concensus on what we have to do to get fast surfing. I bought a very capable iMac and have a fast internet. Doesn't matter which company I call - no one has an answer that works. It's really frustrating and a waste of time trying to troubleshoot these systems. Somewhere while doing these things my printer lost its wireless connection and now the whole printer icon is gone at the bottom - just a ? mark. Are we having fun yet?!

    In Safari Preferences > General Set new pages to open in empty page so it doesn't have to load all the top sites every time you want to open a new window or tab.

    Thanks - that seems to be making a difference!

    If you are running Mavericks 10.3 then you will find IPV6 is enabled by default , turn it off unless you know your network or isp is running V6 ,


    You will find it in the networks /advanced tab and you will need to turn off with a terminal command ;


    networksetup -setv6off wi-fi

    networksetup -setv6off ethernet

    Lots of people are seeing Safari page loads that are slow or stall; this can be intermittent. Many cures have been suggested, many of which seem to work, at least for a while. So many things could be up. I can only report what worked for me (meaning so far, in turn meaning 24 hours -- but the most persistent fix of all).


    I looked at the logs in and saw vast numbers of the the following report:


    4/8/14 9:05:57.722 PM acwebsecagent[327]: Connection : Auth key is not provided or is invalid, applying connection failure policy. CMode : 2 TMode : 1

    4/8/14 9:05:57.722 PM acwebsecagent[327]: OnConnectionFailure : Fail Open - Reason = Unable to verify the license key


    Repeated over and over while Safari was running, over 200 reports in a minute. Googling revealed this to be a component of the Cisco AnyConnect VPN package, something not needed for routine VPN work but that creeps in as part of the default installation. Deleting AnyConnect and reinstalling it without the web agentcwas seems to have been the fix for me (famous last words). There has been a number of discussions about this on this site.


    You might try looking at your Console logs to see if anything funky is going.

    I would want more specific instructions on how to delete AnyConnect & reinstall it. Anyway, why isn't Apple fixing Safari & default settings so we can enjoy fast web browsing? Time for some updates?

  • pzeitler Level 1 Level 1

    _If_ AnyConnect is your problem... it actually comes with an uninstaller (should be in Application/Cisco/). If you then re-install the software, the installer should offer a screen with installation options - the optional bits will have checkboxes. Make sure those are not checked. You will then get the core VPN app but not (the apparently evil) acwebsecagent.

    I just wanted to chime in to thank Rom 1210. This solution worked for me.

  • dstebila Level 1 Level 1

    I was having the same problem, with Facebook and Wikipedia no longer loading.


    I second NGT20V's recommendation to turn off IPv6.  I didn't use the command-line option, though.  Instead, I went into the Network preference pane, then Wi-Fi, then Advanced, then TCP/IP, and set "Configure IPv6" to "Link-local only".
