Safari Web Content
I am running the following
Maverick - 10.9.2, with Safari Version 7.0.2 (9537.74.9)
This build of Safari seems to be incredibly slow, not only when it opens but when you open multiple tabs, the iMac stops reponding, unable to use any applications until Safari starts again. Multiple instances of Safari Web Content are running
I have removed all Extensions, and have disabled Plug ins - any suggestions?
Many Thanks
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Slow system response due to Safari Web Content CPU usage
I have about 200 Tabs open and a DSL line. Safari Web Content frequently uses near or more than 100% of my CPU time, and the computer runs dead slow.
How can I modify Web Content so that it does not refresh tabs in the background?
Maybe I can at least get a "toggle" to control when it tries to access that huge junk server at "deploy.akamaitechnologies.com" ???
Right now its taking over 30 seconds to respond to clicks, and then the same sort of delay before drawing the new screen.Hi..

200 tabs open using DSL ..
Of course it's going to slow your Mac down. Too many open tabs simultaenously on a DSL connection.
You could try empting the Safari cache more often but I doubt that's going to help much with that much content running on 200 tabs. And it won't make any difference regarding servers. -
Hello Guys.
I have this Java pop up for several weeks now and no amount of restarting my Mac will make it go away. Also, when I go to my force quit menu, it insists I have this "safari web content" running, and I have no idea what it is. They might be related, I"m not sure, but how do I make them both go away?
The java pop up prompts me to install java (and I already have installed it, multiple times, so no use there).Oh my gosh. okay here we go. I do see the "Facebook video calling" plug in you spoke about. I know what the silverlight plugin is (that's for an exam I needed a while back but I don't think that's the problem). What should I do now? I can't thank you enough.

Safari Web Content consuming all my memory
I'm having a problem with Safari Web Content.
I've jst re-loaded Mountain Lion in a brute forcve attempt to resolve my issue, but it's still occurring.
The issue is: with very little running, if I run Safari and bounce around a few websites, I can easily consume all my memory. I end up with this:
As you see, Active memory is too high (before this test I had Mail open, and Avtive memory was about 2GBm what you might expect normally).
Actibve memory had actually peaked at about 3/4 of the total, but then some must have got swapped out to Inactive.....giving us the picture above.
But look at the Real Mem occupied by Safai Web Content! That can't be right, surely.
Nevertheless, I'm led to believe that OSX's memory management algorithm's will swap out Inactive for Free when it is required....well, this isn't happening. I saw Free memory down to 7MB at one point, not a typo. Everything grinds to a halt.
If I am patient, and try to Quit Safari, I end up back here:
Clearly showing that if I manage to kill Safari, the memory gets freed up again.
I understand why OSX wants to handle memory with the Inactive concept - "you've just closed Word, but maybe you'll open it again in the next ten minutes so we'll leave it in memory, inactive, so when you try and open it, it will open really quickly". Right now, I'd rather turn that freature off and have memory behave more primitively and take the hit on re-opening.
As I mentioned, I reloaded OSX Mountain Lion and the problem persists. When you re-load or upgrade your OS, there are many configuration settings (desktop, mail, safari) that are kept so that the upgrade looks seamless; clearly whatever is corrupting me here has been kept also. For that reason I'm loathe to go to Mavericks, because I presume the same corruption would exist (and also I hear Mavericks is still a bit shaky with the native Mail app).
What config type files should I look to safely delete and have the OS rebuild? Any ideas?OK, so I tried a Safe Boot. It wired 5GB of memory, and for a while I thought what was left would behave itself, but within about 10 minutes I consumed everything again.
Here's the before:
And here's 10 minutes later, after bouncing around a few websites:
I also tried firing up Safari, going to Facebook, and letting it sit for a while. No effect.
So, the problem occurs when visiting multiple sites - memory isn't getting released properly.
I think I'm left with a move to Mavericks. -
When I am in e-mail, I sometimes get the spinning color wheel, which lock up everything. when it doesn't go away, I see on the activity monitor, that CPU usage is very high (99%), for a process calles " Safari web content'. When I click on the proccess and quite, the CPUusage goes way down. Problem is that I have to then log back in to e-mail. What can I do to eliminate this proble. thanks
How much FREE RAM do you have when this occurs. It's easy to tell, when it beach balls open Activity Monitor (Applications - Utilities - Activity Monitor) click the System Memory tab and note how much FREE RAM is listed. If it's 500MB or less it's time for a RAM upgrade.

Safari Web Content - Constantly using CPU time even when no tabs
Hello,
I have a MacBook Pro Retina (2012), with 16GB of RAM. It is running OSX Mavericks (10.9.4). Recently, I have switched from using it with multiple external monitors, to using it on its own. Here, I have noticed unusually raised usage temperatures - even without any applications (other than Safari) running. Looking at Activity Monitor, it seems Safari Web Content (com.apple.WebKit.WebContent) is constantly using one of my CPUs. Whilst it does not affect the speed of the computer much, it does mean that "idle" temperatures are significantly raised, which is a pain when I am using it on the road.
I have done the following, all of which have not succeeded:
Disabled all Safari extensions
Cleared the cache
Closed all tabs
Sampled the process - unsure of what the output of this means, but if you require it, then I can post it here.
I am unsure what else to try. Currently, the only action that resolves the issue is completely quitting Safari - obviously, this isn't something I can really do for normal usage.
Has anybody come across this before? Is there anything more I can do to investigate the issue? Finally, is there a known fix for this problem?
Thank you in advance,
RichardDo you have any of the following installed:
anti-virus/internet security software?
"Cleaning" or "tuning" software?
third-party backup software (not Apple's Time Machine) that came bundled with an external hard drive?
online backup software (Carbonite, OneDrive, GoogleDrive)?
Also please do "About Safari" from your Safari menu so we can verify your version. On July 11, Apple inadvertently posted a Seed release of a Safari version still under development for the next OSX version. People who had updates set to "automatic" got the "not ready for prime time" version. If you have Safari 7.1, you were "gifted" with that little bag of post-processed cattle feed. -
Any fix for Safari Web Content 100% cpu?
Last I checked, the only fix for this was to restart the browser. Of course, it eventually comes back. My cpu stays between about 75% to 99% because of Safari Web Content process.
Besides restarting the browser, has any one run across a fix for it?From the Safari menu bar, select
Safari ▹ Preferences ▹ Extensions
Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit. -
I click on the Safari logo, page opens but then quickly after closes and the message "Safari Web Content quit unexpectedly" opens with a whole load of computer jargon below.
Any ideas how to fix?
ThanksThis crash is caused by a bug in the way Safari synchronizes with iCloud.
Uncheck the box marked Safari in the iCloud preference pane. You may also need to do as follows.
Back up all data.
Triple-click the text on the line below on this page to the clipboard, then copy it to the Clipboard (command-C):
~/Library/Safari/Bookmarks.plist
Quit Safari.
Select
Go ▹ Go to Folder
from the Finder menu bar. Paste into the text box that opens (command-V), then press return.
A folder window should open with a file named "Bookmarks.plist" selected. Move the selected file to the Desktop, leaving the folder open.
Relaunch Safari. It will open with the default set of bookmarks. Delete them all. Select
File ▹ Import Bookmarks
from the Safari menu bar. Import from the bookmarks file you moved to the Desktop. Arrange the bookmarks as you wish.
Select from the menu bar
History ▹ Clear History
and confirm. As far as I know, you don't need to reset Top Sites, but I'm not sure of that.
You can then try to re-enable Safari in iCloud. It may start to crash again. In that case, you'll have to leave synchronization disabled until a more permanent solution turns up. Sync bookmarks with iOS devices in iTunes instead. -

Reinstall OS X. That will also reinstall a new copy of Safari for you.
Startup your Mac while holding down the Command + R keys.
From there you should be able to access the built in utiliities to reinstall OS X using OS X Recovery. -
Disk Churning by Safari Web Content
Starting about four or five days ago, Safari Web Content is almost constantly using 25% - 30% of my CPU, and my drive is beign accessed almost constantly (reading and writing hundreds of GB each to my data drive). At first, it only affected my wife's account, not it's affecting every account on the machine. There are brief pauses (20-40 seconds), but I usually hear constant disk access. Looking at memory access, nothing seems fishy, so I don't suspect it's something like the OS using my external data drive for swap space. I'm more than stumped at this point.
RayA new data point:
Somehow our iCloud connection was "lost" and I had to re-login into iCloud and re-set the option to sycn bookmarks. While this was happening, I kept getting alerts that bookmarks couldn't be changed because iCloud was sync'ing. What's interesting is that Safari was "idle" in the background at the time. I wasn't using Safari, but it was busy churning away.
I've already re-set and even totally deleted all of our bookmarks, multiple times since upgrading to 10.8, so I don't think yet another reset and bookmark purge is going to help.

High CPU with Safari Web Content
On my MacBook Air with MacOS X 10.9 when using Safari I would notice my computer getting hot and my fan going on. Using Activity Monitor the CPU was 99% for the process Safari Web Content https://gist.github.com. I Force Quit that process and it stopped but would eventually get hot again. I do not have any pages open to gist.github.com but I am looking at pages from github.com.
Any ideas of how to stop this behavior, or why gist.github in the culprit?I'm seeing the same issue with a rouge Safari Web Content process on gist.github.com. I don't have any gists listed in reading list and the process restarts even on a fresh start of Safari.
I wonder if it could be an extension. I have 1Password, Shut Up, Ghostery, Pocket, ClickToPlugin, AdBLock, and Pinbar Beta installed. DonnieM51, do you have any of these installed?
I'm going to try removing or disabling them one by one to see if it helps. -
SafariDAVClient and Safari Web Content hogs my iMac
I am running Mavericks 10.9.3 on my iMac 27", 2.7 ghx Core /i5. Frequently the browsing becomes worse than sluggish, actually at a stand still. If I put my mouse point over Safari, it shows the rotating BeachBall. If I start Activity Monitor, Safari, SafariDAVClient and multiple copies of Safari Web Content appear to be the processes using the cpu power (I have one cpu with four cores). Also, no surprise, Flash Player (Safari Internet plugj-in) is using around 5% of my CPU even though it is only used in a tab of a window which is fully hidden. I am not running any movies on any page. I wish I could be sure which adware might be using the excessively overused Flash plugins and wasting my cpu power. In theory there should be no flash contents being processed.
I've seen this problem since OS X Lion and it has continued through Mountain Lion and Mavericks. With Snow Leopard I used to be able (on the same iMac or its predecessor which was slower) four or five broswer windows each having 5-7 tabs. These open web sites usually didn't not involve animation except for what advertisements did. Since updating to Lion and worse with each release since then my performance in browsing has done a nosedive. To put this in context, three years ago, at work I ran a moderately speedy PC (not as fast as my iMac) with Windows XP. XP didn't perform as well as Snow Leopard but it clearly outperformed every OS X system I've run since then. I noticed a clear step backwards at each new OS major release. The dot releases in between the major releases didn't have a noticable good or bad affect. Some bugs were fixed, a very good thing, but performance stayed as bad as it was before the update.
Don't misunderstand me, I rather like OS X. In featuers and usability it tops Windows any day (through XP, don't get me started on Windows 8, I never used Windows 7).
I have tried other broswers. In turn I have used Safari, Chrome, and Aurora (Firefox alpha) exclusively. when I make the switch things get better. But in a day or two, they bog down again. Chrome is probably my favorite overall but Safari is good in most ways. I've had issues with Firefox besides performance. My daugher recommented Aurora as working better but it is an alpha release so less stable.
Please do not refer me to the discussion at https://discussions.apple.com/thread/3204349?start=0&tstart=0. It does not work with Mavricks. It tells me to turn off Bookmarks in SysPref/iClouce - there is no Bookmark check box at the moment. It also tests me to rename two files name bookmark.* in ~/Library. There are no such files. ~/Library only contains directorys and a search using Find ~/Library |grep -i bookmark had no matches when run in Terminal.
Any other suggests relevant to Mavricks?

Mail and Safari (web content) hog the CPU
Ridiculous proportion of CPU is hogged by Mail and by Safari, causing sluggish performance of all applications
Never experienced this before upgrading to Mavericks.
Any suggestions?I have an update which seems to have worked for me - things were getting so bad, streaming audio was dropping out, so I had to do something.
I downloaded and ran the latest version of OnyX which told me I needed to repair my boot drive - this process took about an hour, then I cleared out pretty much everything using the OnyX Cleaner.
One of the things I have running is Little Snitch (mainly because I want to know what's being sent out from my machine). When I rebooted for the final time, some Google app (ksurl) kept asking for permission to connect to Google. I'd previously blocked this, but given all the problems I had with Safari, I decided to let it go this time.
Now, I don't know whether it was the reboots, OnyX cleaner, the boot parttition errors or Little Snitch, but I've been running for over four hours now, using Safari and Safari Web Content is constantly below 2% CPU, audio streaming is working without dropouts and overall everything seems to be much smoother. -
Hi,
I recently upgraded to Safari 6.0.
In the previous version of Safari (whatever the latest 5.x was), when the process "Safari Web Content" got too large (memory-wise) I could force-kill it using Activity Monitor. The behavior when that happened was that most (if not all) of the Safari Web Content memory would be freed, and all of the open tabs on Safari would be reloaded. This was very good behavior, IMO, because it allowed me to retrieve some memory without losing any content (other that now being unable to go back.)
In Safari 6.0, when Safari Web Content is killed, the entire Safari process is killed, and you have to start from scratch.
Was this an accidental feature (aka a bug) in Safari 5.x, or was this change intentional? Is there any way to free up memory in Safari 6.0 without killing the whole thing? Safari 6.0 seems to continue the trend of Safari being a real memory hog (apparently much worse than Google Chrome), and the behavior of 5.x was very useful in that regard.
Thanks,
