Just installed MACOS 10.6.8 and Safari as well as anything connecting to the Internet is extremely slow. Checked ISP and the speed is fine. Verified access via my IPAD through the same network is fine. Safari takes forever to make connections, Mail is the same way. Checking for software update takes 20+ minutes. Once a connection is made response time seems to be fine, however, moving from Link to Link is dreadfully slow.
iMac
Create a new User... go to System Preferences > Accounts > "+" (make it an admin acct) and test speed in this new account, if it functions normally, the problem is isolated to your User and not systemwide. Then we can take the next steps.

I've been experiencing the exact same problem since upgrading to 10.6.8. TCP connections take an inordinate amount of time to establish (2-3 seconds), but once they run at full speed. This is affecting all applications... Safari, Chrome, iTunes, App Store etc.
Running Chrome Speed Tracer it appears that its intermittent... some connections establish just fine but about 1/4 don't and drags down the who page performance.
My iPads, our iPhones and our Vista laptop are not having any problems. I've also verified that I can ping remote sites without any delay (~50-70ms which is normal for my connection) and DNS queries are resolving quickly as well. Again it seems something is unhappy on the TCP stack (ICMP, UDP are unaffected).
I'm running a 2010 iMac i7 (iMac11,1) with 16GB and I'm using wi-fi.
I tried created a new admin account as suggested, no affect.
Any other suggestions would be greatly appreciated... this is very frustrating.
Yes that's exactly what's happening. I prettymuch have the same setup as you.
I tried running ie under parallels and it seems much faster for some strange reason. Perhaps this supports theory of tcp io stack problems
Also I believe everything was fine when I was in safe mode. I still need to confirm this. I am currently out at the moment. You might want to try it and see. It will at least give us a clue.
Others things I have tried include
Reloading the 10.6.8 release
Resetting safari
Fix disk I had a few issues and repaired them. No help.
I have exactly the same experience: All external network access is slow after I upgraded to 10.6.8.
I tried:
Reinstalling 10.6.8 (the full version .dmg this time instead of just the update)
Resetting Safari (but Firefox also has the problem)
Recaching kexts
Repairing disk permissions
Using wired and wireless access
None of this had any effect at all.
Other devices on my network works fine (e.g windows 7 and linux machines)
I tried running chrome in a windows 7 fusion session and that works fine. It is only the OSX installation that
has the problem.
The same page takes 3 secs in WIndows 7 Chrome and 50 secs in Safari native OSX.
I have been looking at this link: http://technocrat.net/d/2008/8/23/48134/
It seems go indicate that there could be a router problem.
At least in Firefox you can see that the DNS lookups take a long time...There is plenty of time to check which banner adds are loaded on the sites.
Any suggestions anybody?
I have exactly the same problem here after upgrading to 10.6.8 on my MBP.
Also also tried all of the above measurements, but nothing worked yet. iPad and iPhone just work fine.
The strange thing is, that I took my MacBook to another Wireless Lan Hotspot and everything was fine. Connections seemed to work at a normal pace.
I have a Time Capsule here where all of my Clients connect, which is connected to a Router/Modem that establishes the Internet connection.
Any suggestions what could be the problem?
**** PROGRESS *****
Well I just booted up in Safe mode
From Terminal: sudo nvram boot-args="-x -v"
In safe mode, mail and Safari are now behaving properly - no response time issues. So something possibly in the late startup is causing this problem.
Continuing to investigate
Having the same exact problem. Updated to 10.6.8 and the problem arose. Suspected that it was the Safari 5.1 beta causing the problem, so I downgraded to the public release 5.0.5 and the problem persists. Firefox has the same problem so I agree, it appears system-wide. Very unhappy with Apple right now, they better fix this fast.
Is everyone on 10.6.8 having this problem or is it seemingly random?
1. Okay so SAFE MODE appears to get around the problem.
2. I just disconnect my MAC from all Ethernet and Wireless Ports (everything) and now connected through my iphone via bluetooth and everything is back to normal. So avoid internal ethernet and wireless gets around the problem. Not in this case I am still going through the SAME wireless ROUTER (Wireless Extreme) that my MAC was going through... VERY VERY ODD....
I think their may be a "ROUTING" problem being introduced somehow,
back to the drawing board.
NOTE: In the past few days I have load 10.6.8 and Motion, Compressor and Final CUT X, I have Final cut Pro existing. Just in case some of you have this as part of your configuration - maybe a connection somehow.
Apparently 10.6.8 fixed some IPV6 problem, perhaps it has introduced an IPV4 problem along with it...
I found a solution/workaround on my system.
Going off StonyBoy's link I set my iMac's DNS to Google's Public DNS, bypassing the DNS proxy on my router. Everything's back to normal.
So now the question is what is it about my router that 10.6.8 doesn't like (it's an Asus N56U for the record).
Worked for me too. Now the question is why?
My router is from Bell Canada. My Time Machine is acting in BRIDGE Mode.
I have report the issue to APPLE
# 9678726.
Let the experts take it from here.... Thanks thesandbender
ds store. I have IPv6 turned off, my router doesn't support it so disabling it was one of the first things I tried since I can't really use it anyway.
Interesting... I also have an Asus N56U and am encountering this same problem.
On a side note... great router, huh?
Hi
Didn't make any change. Safari, Chrome, Firefox is still very slow. I addition I run parallels, and in XP the browsers are running at normal speed.. Really stranges - and anoying. Any further suggestions.
10.6.8 Internet/Safari Response time Very Slow
