OS 10.8x Slow Internet browsing

Changed the MTU and IP6 back to automatic and I have the same experience,

If it is the first time I open a page, it can take anything between 10 and 25 seconds. If I open the page a second time, it opens quickly, but if I close the browser and try again it takes long the first time.

@SauRoNZA - I changed MTU to 1453 and changed IPv6 to Link-local-only.

I get mixed results now. If it is the first time I open a page, it can take anything between 10 and 25 seconds. If I open the page a second time, it opens quickly, but if I close the browser and try again it takes long the first time.

I also tried the following before I made the changes to the MTU and IP6,

1. In Safari, go to prefences and remove Cookies, then Develop menu, and empty caches.

2. Shut down the machine and unplug it for one full minute. This resets the SMC.

3. Start up in safe mode (hold shift key after hitting power button until you see the apple icon on screen) then go to Utilities folder in Applications and open Disk Utility. Select Mac HD on left, then Verify Disk. When Verify Disk is completed, click on Verify Permissions. After completing this step, if any permission problems are listed, click on Repair Permissions.

4. Shut down the computer, and start up while holding 4 keys at the same time; Option, Command, P, and R. Hold these keys down until you hear the computer chime twice. This step resets the PRAM.

...is whatever network device you have in your hands. A Mac on the other hand is different. We Mac users have no need to capitalise every word :D

The speedtests show a marginal difference as far as I am concerned. My suspicion therefore lies in network setup. OP, is it possible to give the Macs a static IP and see if a difference is noted?
 
Hi all, thanks for your feedback. I'm off sick at the moment. I will look at this problem again when I'm back in the office.

Thats for non-Apple hardware. Hardware thats inside your Mac has built in support and gets updated via OS updates. You cannot download standalone drivers for it. However, if you have some knowledge of kext editing, you could modify and install you own drivers on you mac, for whatever reason. The only time i've ever done that was on a hackintosh when I wanted sleep mode enabled on a bluetooth adapter and it was a pain to get working.

While in Safe Mode do you get these same results with slow browsing?

If the problem goes away in Safe Mode (which only loads the bare minimum) it could very well be one of your browser plugins causing you all these headaches.

Yeah printers are a wee bit different as they come with a PPD file that needs to be dropped in a location and some of them have the usual software of their own which eats your machine alive.

More of than not the driver is already there but it's things like the "Press button to scan" stuff that needs more software loaded.

Hi

Did you manage to find a solution?

I am experiencing similar problems.

Thanks
 
Some people have indicated that resetting NVRAM/PRAM fixes this. There are some settings stored in this ram which persists after a restart. These settings may not be ideal for the OS after an upgrade.

Try the steps in the article. Maybe it helps.

Another possible solution is disable wifi and enable it again.

Also resetting Safari.

Alternatively change browers. I believe Chrome is good. I use Firefox.

You must have skipped this part: "Note: OS X does not store network settings in NVRAM / PRAM. If you are troubleshooting a network issue, resetting it will not help."

NVRAM / PRAM only stores info in memory for while your machine is in sleep mode which helps your machine to wake and continue where it was. That info has nothing to do with networking at all and is reset simply by shutting your machine down.

No didnt. The settings in Safari are not network settings. They are application settings. And I posted it beacuse it did work for some who also experienced the same problems. As I stated in my post, its something worth trying.
