Safari is v-e-r-y slow
Hello, I have Safari 5.0.6 with G5 1.8ghz (hard wired to the router) When I surf you tube, or some other sites, in the past 3-4 months, Safari has become very slow and it is almost impossible to view any videos. It takes forever for the pages to load... but when I use Firefoz or Google chrome, it load much faster.
Internet connection is fine, cuz I even use my Safari on my iPod, (via wireless) and it works great there!
was told by a genius to re-install Safari... but I dont want to loose my bookmarks!

Michel,
You symptoms and their absence from other accounts makes me wonder if you have an incompatible extension or plug-in. Commercial anti-virus and/or internet security software can also create havoc.
Do Safari > Preferences and click on the "Extensions" tab. Is anything listed?
was told by a genius to re-install Safari... but I dont want to loose my bookmarks!
Although I think a reinstall is premature at this point, you can save bookmarks and reapply after reinstalling a browser. Before reinstalling, do File > Export Bookmarks... and save it to some place easy to find--I usually save it to my Desktop. After reinstalling (which may not mess your bookmarks as they are stored in your account, not the Application folder), doing File > Import bookmarks... will restore them.

I updated my iPod touch 4g 64gb to iOS 6.1 and now it's been very slow, safari keeps crashing, apps being very slow and crashing ? Can anyone help ?
Next
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>Safari and Clear Cookies, Data and History
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device. -
update to IOS 6 has been a nightmare. Facebook would allow me to save pictures unless I granted access to my foto album. Does this mean my pictures are going be planted all over the web? The safari keeps crashing and loading is slow. Most infuriating is that YouTube was deleted from my entertainment apps and I now have to pay for it if I want it back!! This is a bloody disgrace.
Back up all data.
Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin. -
Safari 3.01 beta (Windows) too slow on some machines
On certain Windows machines I have, the Safari 3.01 beta is incredibly slow, as reported by a few others in this forum. The pages--any page, from the simple Google search page to local .html files--will ultimately load after minutes, often with pictures and other embedded objects timing out. That this happens with local .html files as well as sites readily accessible in other browsers indicates it's not a connectivity or networking problem per se.
OK, I've now uninstalled and re-installed, with various combinations of clearing out the user settings under the %USERPROFILE%\Application Data\Apple Computer or not, and still cannot get around this problem.
I cannot identify anything in common between the machines except for the Safari Beta and that they are Windows XP Professional SP2 systems with all current updates as of now. The particular machine from which I'm posting this has the problem; it's a Celeron 4/2.6 GHz with 1 GB RAM, so it shouldn't be an issue.
Incidentally, this is really an alpha release that doesn't remotely deserve to be tagged as a beta; I know that catching the WWDC deadline to publicize the release was important, but Apple should come clean as to the level of testing and alpha status of this product, even if it is free, considering it is being so publicly advertised and wrongly hyped as fast. I'd trade stability for (reasonable) speed any given day, especially for those of us whose primary interest in the product is Web design QA under different browsers/rendering engines.
Any suggestions?whaterverfdsa wrote:
Is the problem the system/install of OC or the profile/user. Try reinstalling OC on the "fast" system but use the profile/user of one of the "slow" systems.Have tried the other way around (tried with the "fast user" on the "slow machine" :o)... still slow..)In which case the problem is unlikely to be "server-side". You can also review the Outlook Connector debug logs to see if there is some indication of why the delay is occuring.

I can't seem to get any IMAP telemetry logs from outlook connector....
I wasn't quite sure what was meant when the docs say create a directory imap/<userid>. What is the userid? So I tried some variations. This is for user in the default domain. Tried jdoe, [email protected] and an alias address (it was the mail-value in ldap). Nothing appeared when using the outlook connector, but when I added the account as an imap account in outlook, logs appeared in the jdoe-directory... Doesn't the outlook connector use imap???
Yes it does. Telemetry logs are only created for new connections after the telemetry directory for the user has been created. So you would need to restart Outlook to get the log files.
(btw: imap idle doesn't seem to work when using outlook connector, but works when using imap account...?)It definitely appears Outlook Connector does not make use of IMAP IDLE. A quick search didn't reveal any existing enhancement requests to have this functionality added.

Safari loads (freezes loading) webpages very slow on iPhone 4
Hi!
I have a problem with Safari on my iPhone 4 (4.2.1). Since I upgraded to 4.2.1 a week ago Safari is very slow and in 80% of time wont load webpages with first time when in 3G mode with strong bars. Well it loads them but very slowly (It takes approximately 20-30 seconds to load google or other pages). Maybe it would be more precisely to say that it starts to load, than the blue progress bar just stops at around 1/2cm and than after 20-30 seconds it actually starts to open the page and the blue progress bar continues to move. Sometimes (not often) after those 20-30 seconds I get message that page can't be opened cause server stopped to respond...
What is important to my mind is that if I press reload while Safari is loading a webpage it opens fast as it should. So it usually works with second try.
Since I noticed this problem after I upgraded to 4.2.1 I think those two things have connection (4.2.1 and Safari problem) but I might be wrong.
This is happening in different locations around the city and it is not problem with coverage...I have three, four or sometimes even 5 bars 3G.
Anybody having the same problem or can help me with some advice?
Thank you!Safari Problems

Safari 8.0 loads pages very slow
Why does Safari 8.0 load webpages so slow now that I have installed OS X 10.10 - even the Apple.com page is painfully slow to load.
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?
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
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?
Open the iCloud preference pane and uncheck the box marked Photos, 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? -
Recently downloaded Mac OS X Mavericks and Safari has become noticeably less responsive; slow to load web pages. Also, when Safari is open, the Finder randomly comes to the front. Any ideas?
In fact, I am runing some plug-ins: ClickToPlugin (Flash blocker), Collusion and Disconnect.
There is quite a history of new versions of Safari breaking third-party plug-ins/extensions becasue the plug developer did not have an updated version available by the time the new Safari version dropped. What you report--worked fne before but won't now--is exactly what history says happens in such a case.
First, turn off all third-party stuff and see if Safari smooths out. Alternatively, create a new user account and, from there, test Safari in its native state with nothing added. That is a good diagnostic to see if the issue is a plug or extension.
If either of those helps, check for updates to the add-ons. If the developer is slow in reacting to the updated Safari version, (not unheard of), stop using that extension until an update is available. -
Upgraded from 10.6.8 to Yosemite and now safari crashes and everything is extrememly slow
How do I fix my computer after upgrading from 10.6.8 to 10.10.1? Safari quits responding constantly, my computer runs so slow it is virtually useless. I have an early 2008 iMac, 2.66gHz Intel 2 Duo Core, 2 G Mem. I got this report from EtreCheck

Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts. -
Is there a way to boost Safari? I'm using Snow Leopard 10.6.8, Safari 5.1.7 which has become very slow, almost dead. Many thanks!
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:

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.

Not sure if this is the best place to post this problem. If not, would appreciate advice on where to go. My problem -- I downloaded the new 3.1.1 Safari the day it came out and every since, it's been like having dial up. Loading pages, doing anything on the web is painstakingly SLOW. I read that others are having this problem and that I should download again -- which I did. That didn't help. I've called my cable company and my computer checks out perfectly -- upload/download speeds are tops. It's definitely Safari -- all started with that download. I'm on a Mac G5, OS 10.4.11. I've emptied cache, cleared history, etc. Any suggestions? Is it possible to just revert back to the old version?

Safari 3.1 setAttribute very very slow!!
Hi I'm developing an application using SVG and CSS and, after upgrading to 3.1, I discovered that the rendering of an SVG component after changing its class attribute is absolutely slow: it takes forever (literally).
It is a simple element.setAttribute('class', classname).
This only takes effect AFTER I reload the page, which obviously, is not what I want.
Is there a simple solution to this? does anyone else have the same problem?
As a last solution I would like to downgrade to the previous 3.0.4 version. Can anybody point me to a working http address where I can download an old version of Safari?
Thanks,

Safari and other apps are very slow
I am frustrated because I have goodled and tried everything. Safari and other apps on my MacBook Pro are loading very slowly. This was not the case about a month ago. I purchased this Macbook in October 2014 and it should not be as slow as it is. What can I do? I have changed a few settings and made some adjustments and the performance is still the same. Help.
When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created. -
Safari 4.1.3 Running Deathly Slow and Being a Memory Hog

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:

After upgrade mac os to 10.8 the safari surve net is very very slow
Hi my imac using the Mac OS 10.7 and after upgrade to 10.8 the whole imac become very slow especially safari and apps features. May i know what happen to my iMac?
First, back up all data immediately, as your boot drive might be failing.
Take these steps when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting. -
Can somebody tell me what is going on with the last update of Mountain Lion 10.8.2?? Since then my computer is pretty much slower and blocken on Safari.
First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.
