Why is Safari running slow on my MBP?

It just recently started to slow down. A few hours ago, I experienced it so I just turned off my MBP to, hopefully fix it, but Safari is still going slow. Yesterday, it was running fine and I was loading up pages fast. Now, when I ever I go to a new page or click a link, it pauses and the address bar above loads to about 3cm and the spinning color wheel spins for about 5 seconds until the new page loads. It does it for every thing I go to. Trying to ask this question probably took a minute to get to when it should only be a few seconds. I've tried Google Chrome and Mozilla Firefox and it is fine. When I enter a web address or click a link, in a few seconds, the new page shows. I really don't want to move to a new internet source because all my bookmarks and saves is on Safari. Is there a way to fix this?

Since Safari freezes before you can troubleshoot, boot in Safe Mode then try troubleshooting Safari extensions and third party plug-ins.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
Once you are in Safe Mode, click Restart from the Apple () menu.

You're going to have to be more specific and include some details.

Why is Safari running so slow under Mountain Lion?

Why is Safari running so slow under Mountain Lion?

I have other mac's on my home network that are still running Snow Leopard and the are performing well. I wanted to use the iCloud so I upgraded and instantly started experiencing the slow down, to the point of ridiculousness. Other function are mixed some normal speed, others a day on the beach with the spinning ball. Firefox is at full speed, good thought, haven't checked Chrome yet.
Last night and hooked into a projection unit that adjusted my screen resolution for a presentation and after the event my Mac reset back to the normal settings and Safari launched and is running normal speeds so far. In the past there have been issues with performance speeds and certain resolutions, has anyone had similar luck or is this a fluke?

Why is my safari running slow after updating my mac?

My safari is running slow after completing a software update. I have cleared the cache. It did not help.

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
If your browser is Safari, then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Any change?
If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
Stop plug-ins to save power
Any change?
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If Parental Controls is active for any user, please turn it off and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Why is safari running so slow

Everytime I open safari all the sites even apple takes forever to load and is not internet connection I even went out and bought a new modem thinking it was the modem but is still running slow, wifi or ethernet.

Since this is the forum dealing with the MacBook Pro Hardware, your question will be best answered in the Safari forum. There are several steps that need to be taken, but you need to determine if Safari is the culprit or your network.

Safari Running Slower and Slower

Hello...No idea why, but Safari is running slower and slower lately for me on my MacBook Pro.
Any suggestions on how I may be able to troubleshoot this?
Thank you.

The following usually works on both Tiger and Leopard:
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
If not, MacFixit have published a very detailed (very!) article on speeding up a slow Safari, here:
http://www.macfixit.com/article.php?story=20070416000657464
Many, including me, have also followed the advice given by others here to add DNS codes to their Network Settings, with good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
Click on Apply Now and close the window.
Restart Safari, and repair permissions.

Why is safari so slow

This is my first time using a mac...i love the computer but this safari is so slow. the blue bar is taking forever to fill up and sometimes it gets stuck. i've tried opera and firefox but both seem much slower than my windows pc. is it just me or is this a common problem and are there any remedies?

I'm assuming that when you say Safari is slow, you have tried another browser like FireFox... If you haven't that may be worth a try just to be sure its not a network issue. (Highly recommend FireFox)
After only a week I wouldn't think cache or Java would be a problem, but here's a few things worth trying...
Clear Safari Cache: Pull down the Safari menu -> Select: Empty Cache
Clear Cookies: Safari -> Preferences -> Security - > show cookies - Clear all
You can also Reset Safari: Safari -> Reset Safari (this will remove history, auto fill info, basically everything.
Clear the Java cache, open Finder, go to Applications -> Utilities -> Java
In the Java folder there are normally two Java Apps: "Java 1.4.2 Plugin Settings.app" and "Java 1.3.1 Plugin Settings.app" .
Quit Safari, and Run (double click) each one.
In Java 1.4.2 you should see a "Cache" tab and or a "Clear" button. In Java 1.3.1 you will see a Cache tab and a "Clear JAR Cache button.

Why is Safari becoming slow and unresponsive?

Ok - I have exactly the same problem. I can run safari and use it. After a short while it becomes slow and unresponsive. When I quit I get the rainbow ball of death and the only way I can stop the application is to force quit.
It is definitely linked to a particular network account as the guest account check above shows that it runs fine on another account.
As I watch system memory in actvity monitor while I use safari the fhe following occurs:
1.     free memory gets gradually used up to about 50%
2.     Inactive memory gradually builds to about 50% of total
3.     Then page in and page outs build massively and the swap file goes into overdrive
I have 32GB memory on board but even so it doesn't take long for Safari to gobble it up.
At the same time CPU % shows 90-100% and Real Mem sits around 15-18GB.
By this stage the whole machine is slow and unresponsive as safari ***** up all its processor and memory resources.
I have taken the following action:
1.     reset safari using the reset process built into the app - no difference
2.     deleted the preferences file - no difference
3.     deleted the Library/cache file - no difference
Thought about resetting NVRAM but decided that it wouldn't make much difference because it seems to be linked to a user.
Any thoughts/suggestions on other actions I can take would be welcome.
Are there other cache or preference files that I should be trashing. Can I delete and reinstall safari? I don't really want to have to go through the process of establishing a new user and rebuilding a reasonably substantial docs and photo library and set up.
Help.

You forgot to mention what version of Safari you have, but:
If Safari is getting very slow:
(Presumably you regularly empty your Safari cache by deleting the following file:
Home/Library/Caches/com.apple.Safari/cache.db
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, (including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat ) and further independent information can be read here:
http://reviews.cnet.com/8301-13727_7-57338784-263/free-dnscrypt-tool-enhances-ma c-web-security/?tag=mncol;txt
and here:
http://www.macworld.com/article/1146064/troubleshootdns.html?t=234
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:
208.67.222.222
208.67.220.220
(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:
http://support.apple.com/kb/TS2296
If your computer is part of a network:please refer to this page: http://www.opendns.com/start/best_practices/#your_network 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:
http://support.apple.com/kb/TS3408?viewlocale=en_US
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 later versions of Flash 10.1 onwards appear to have improved the situation somewhat, but haven't completed eliminated it.
For this and other reasons Apple switched their websites to HTML5 in January 2011:

Safari runs slow

Since installing Mountain Lion on my iMac, it seems that Safari is running slower and slower. It seems to find the site I want to visit, then loads a small amount of data, then sits for a long period of time and loads the rest quickly. I have also installed a new cable modem and Airport Extreme recently. I don't run the iMace over the wireless rather on Ethernet from the Airport Extreme. The new cable modem is set up for Docsys 3 and seems to be very fast at times when downloading on iTunes for example. Any ideas?

I signed up for the open DNS service and this seems to have sped up every thing on the net except my apple tv. It is updating its software now and we will see what happens with it!

I bought imac new in 2007-it has safari. runs slow, the color disk shows during then. bought either leopard or snow leopard, but not enough memory to load it- any suggestions? i dont want to buy another computer! thx!

Open up your Finder window & check the bottom of the window in the middle. It will tell you how much HD space you have left.

Empty the trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.). Or transfer/move them all to a photo/movie storage site like ImageShack and Photobucket, 2 of the most popular FREE storage sites.
Get rid of all your video & music files you no longer view and/or listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website. Or transfer them all to a FREE video/movies and/or music storage site.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight!
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app *demo* called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs. Not everyone has the luxury of purchasing an external HD and/or the system requirements for iCloud to store their "stuff.”
Dropbox is a free storage facility software.
You can check with your ISP to see if they offer *free* storage space. Most if not all do now-a-days. There are thousands if not millions of *free* storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + *click* to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s *FREE*.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your *current* printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidently threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a *FREE* utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).

Safari Running slow on OS X Yosemite?

Safari tends to run slow on OS X Yosemite. This happens most of the time when I'm running a Facebook tab (which "whites out") or watching a YouTube video (which is really choppy and "unsyncs" with the audio). The colored pinwheel becomes commonplace and the screen freezes. I thought it would be my internet connection but I've used other browsers such as Chrome and Firefox on the mentioned sites and it works perfectly fine. This problem has happened since I've updated my MacBook to OS X Yosemite back in October. Is this a general problem among all Macs with the latest Safari update Version 8.0.2 (10600.2.5)? If not, what could it possibly be?

Go step by step by step and test.
1. Power off the router. Unplug it from the wall. Wait a while.
    Plug it back to the wall. Power the router on. Wait until all the lights are lit properly. It will take a while.
    Restart the computer.
    Start up in Safe Mode.
    http://support.apple.com/kb/PH14204
2. Delete Caches.db
    Close all windows and quit all applications.
    Hold "option" key down and click "Go" menu in the Finder menu bar.
    Select "Library" from the dropdown.
    Library > Caches > com.apple.Safari > Caches.db
    Right click the Caches.db file and select "Move To Trash.
    Close windows and relaunch Safari.
3. Empty Caches
    Safari > Preference > Advanced
    Checkmark the box for "Show Develop menu in menu bar".
    Develop menu will appear in the Safari menu bar.
    Click Develop and select "Empty Caches" from the dropdown.
4. Delete Cookies
    Safari > Preferences > Privacy > Cookies and other website data:
    Click “Remove All Website Data”.
5. Safari > Preferences > Extensions
    Turn off Extensions if any and launch Safari again to test.
    Turn on those one by one and test.

Why does Lion run slower than Snow Leopard?

I recently loaded Lion on my older MacBook Pro 2.2 GHz Intel Core Duo, with 4 GB 677 MHz DDR2 SDRAM. and it runs slower and the it seems to be hotter and consume more battery power. Are the configuration option that can reduce the power drain?

You may have some mildly-incompatible third-party software, or you may be doing tasks that demand a lot of RAM and 4 GB is no longer enough on a system that has double the memory requirements of SL. Or could be something else entirely. Take a look at Understanding upgrade nightmares* for more information and some potential solutions.

Why is Safari so slow on Mediacom cable internet?

Bought the latest and fastest IMac and it is running slower than my old one.

Try testing your download / upload speeds > http://www.speedtest.net/
For broadband download should be anywhere from 15 to 20Mbps, upload 4 to 6Mbps.
Unfortunately, other uses are experieince similar issues with Lion.
