Safari is very slow only with one user

Hey,

I do have the exact same issue and tried everything you tried as well. See here: Safari not loading pages, other browsers doing fine

I have a question, though: do you use a docking station of some kind or an ethernet adapter? I have two MacBook Air but only one presents the issue. The only difference is that the one with the issue is sometimes connected to a LandingZone Dock. Other than that, I can't figure out what's different (installed both from the same image).

I also have these in my log:

Well, I don't think this will be solved. For now, I reverted to using Chrome and will see if the problem disappears once Yosemite is released.

I have the same problem, but only with www.yahoo.com. 30-60 seconds to load the page, sometimes longer. Chrome loads the same page instantly.

I'm running the latest released version of Mavericks with the latest version of Safari.

Back up all data to at least two different storage devices, if you haven't already done so. One backup is not enough to be safe. The backups can be made with Time Machine or with Disk Utility. Preferably both.

Erase and install OS X. This operation will destroy all data on the startup volume, so you had be better be sure of the backups. If you upgraded from an older version of OS X, you'll need the Apple ID and password that you used, so make a note of those before you begin.

When you restart, you'll be prompted to go through the initial setup process in Setup Assistant. That’s when you transfer the data from a backup.

Select only users and Computer & Network Settings in the Setup Assistant dialog—not Applications or Other files and folders. Don't transfer the Guest account, if it was enabled.

After that, run Software Update.

If the problem is resolved after the clean installation, reinstall third-party software selectively. I can only suggest general guidelines. Self-contained applications that install into the Applications folder by drag-and-drop or download from the App Store are usually safe. Anything that comes packaged as an installer or that prompts for an administrator password is suspect, and you must test thoroughly after reinstalling each such item to make sure you haven't restored the problem.
I strongly recommend that you never reinstall commercial "security" products or "utilities," nor any software that changes the user interface or the behavior of built-in applications such as Safari. If you do that, the problem is likely to recur.

Before installing any software, ask yourself the question: "Am I sure I know how to uninstall this without having to wipe the volume again?" If the answer is "no," stop.

Never install any third-party software unless you know how to uninstall it.

Reinstall the operating system to maybe fix a problem with Safari? No way. I appreciate the suggestion and the time you've devoted to this issue, but unless Apple releases a bulletin indicating they know what the issue is, and an OS reinstall is required to fix it, there's no way I'm doing a reinstall to see what happens. My iMac is pretty clean and I'm pretty disciplined about managing what software is allowed on it.

I think there is something buggered up with the latest version of Safari. It's terribly slow compared with Chrome and it wasn't a few weeks ago.

I'm going to use Chrome until it is well understood what the problem with Safari is, or until Yosemite is released.

Good luck all!

Don't bother with linc's answers, WGQ. He's chain-copy pasting answers without reading threads before eventually pasting the "reinstall" one. I have reinstalled OS X and the OP did too. No changes. So yeah, Chrome for now :-/

I've installed Wireshark and I definitely see some strange things happening when browsing from Safari that I don't see using Chrome.

ClimbToSummit, do you have any remote desktop client installed such as Splashtop? Microsoft OneNote? Do you use iCloud Keychain? I will once again reinstall without any of these and see if there's a difference.

Alright, I re-installed once again after completely erasing Macintosh HD. So far, Safari works fine.

Despite what linc said in my other thread, I still think there was something wrong with certificates. What caused that, I have no idea. I think some other software, maybe even Dropbox (or, in my case, Splashtop which I use to connect to my home Mac from my Air).

My reasoning is this:

- pushing code to Github was failing randomly and analyzing logs from Wireshark, I found that it couldn't authenticate me

- I tried to download Xcode 6 beta 6 from my Apple Developer account and I got an "access denied" error

- most of the failing sites were served through https rather than http. After attempting to connect to one https, all the http ones would fail until I restarted Safari

- Microsoft OneNote would randomly fail to connect to Microsoft servers with a cryptic authentication error

Before re-installing OS X, I also wiped the content of my iCloud keychain. Maybe something was corrupted in it?

At this point, I haven't re-installed anything except Carbon Copy Cloner as I want to make a clean, bootable image. I will re-install my apps one by one and attempt to find the culprit. It may take some time, though, as I plan to make an image after each install.

I am interested with what you find out. My problem is more with links within a site than slow or open failures. I do not user iCloud Keychain or remote desktops or screen shares. Seems to be the Same issue on all four of our macs with latest safari update.

Try to open Keychain Access. If in the top left column you select "System" and "Keys" in the bottom one, what do you see? 4 com.apple.* keys (2 public, 2 private)?

No joy: day 2 after complete wipe and re-install of OS X... and the issue appears again. Many pages or links within pages take forever to load and sometimes issue a time-out error.

The only app I have installed are Pixelmator and Sketch 3.

I give up. Lost too much time over this already. Chrome it is, then.

Hi

I had/have the same issue. I apparently found some workaround, however I'm not sure how stable it is and I also don't really like it.

Basically, for me problem was primarily with SSL sites having certificates issued by Go Daddy (for example Dropbox). It seems to be related to Certificate Recovation Lists and/or Online Certificate Status Protocol somehow.

When I turn these off (in Keychain Access, Preferences, Certificates), the problem seems to disappear. I still have one issue with an application that syncs to Dropbox, but that might be unrelated.

It would be interesting to see if this is really the cause, so if you could try this out I would appreciate it.
