Safari :: Slow System Response Due To Its Web Content CPU Usage
Jun 18, 2012
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 "url..." ?Right now its taking over 30 seconds to respond to clicks, and then the same sort of delay before drawing the new screen.
Bought my Macbook almost 3 years ago and it worked brilliantly but recently (after upgrading to Leopard?) I have become painfully familiar with the beach ball. Before it was blazing-fast. Now it always seems about two steps behind my brain. And that's really slow.
recently my Mac is really slow, slow on startup(took around 1-2hours), and slow on task(more than 5 minutes delayed time on every single task), I don't know what happened to it,
My Mac specs: ¬†
1.Mid-2010 27 inch iMac,
2.Original 4g Ram upgraded to 12g
3.1TB HD has got more than 400gb free space.
5.Using latest Lion(I think it's 10.7.3)¬†
1.Startup tooooooooo slow, take more than 1 hour
2.Extreamly slow on tasks. Without any apps opened, every single click, it turned into the 'colorful fan', for instance, open finder, it took more than five mins, and it's not only the finder, it's EVERYTHING!!!!¬†
What I have done so far:¬†
1.I have reduced the login items
2.I have changed the password login to the automatic login
3.I have tried verify disk permission, verify disk, repair disk permission and repair disk
4.Unplug all unnecessary items(monitor, external drive etc.)
5.Run couple of time of 'clean my Mac', get rid of all the trash.
6.Cleaned the cache¬†
Due to the ridiculous, frustrating startup, that's all I could do, however, none of them worked.
Now I am using recovery HD to reinstall Lion from a disc, but I don't know if it'll work or not.¬†
I don't have another Mac, I don't have backups(don't want to lose my data),that's my situation.

I have a HP Business Inkjet 2800 (no attachments or upgrades) and it works fine on Windows through Bootcamp, but is painfully slow on Mac OS X (10.5.3.) I've always had a problem with Macs and HP printers, but this has become ridiculous.
I have the latest drivers installed, but it can take over 14 hours to begin printing a single image, only about 15-30 minutes for text only. I don't print anything with more than 1 image from OS X anymore. I even tried using a shorter (4 ft.) USB cable.
so I'm wondering if my i7 macbook pro is going to need to go in. I'm having constant freezes and forcing me to force quit programs and even plugging in external speakers there is a good 45 second delay between connection and everything working. Also the volume and brightness control constantly are lagging when I try to use them. Does this sound like the tradtional freezing problem?
I'm running Snow Leopard on a Mac Pro. I often connect to a Linux server sitting at the office through afp. It connects fine, but very quickly the response time of the folders becomes extremely slow. Granted there are fire walls and network magic and whatnot between here and that server that don't exist inside the network at the office. But I feel as if this is a more recent phenomena. Connections in this way have been a little sluggish in the past, but now it's consistently unbearable--beach balls and unresponsive Finder windows. I have an internal RAID pair, and extra drives, and shared connections all talking to this machine.
Which clearly causes the occasional "hiccup" in the system. Like sometimes I wait for folders to load, or like VMWare pausing for a few seconds when trying to access some of the Mac drives. But, for the most part, the system works fast and fine. I've tried to watch the Activity Monitor while accessing the Finder windows on the server. And, all that I've learned is that FireFox is big resource hog, and that Finder barely registers any CPU effort when I click into those drives. Speakeasy tells me I'm getting around 14 Mbps for network speed. The server itself seems to be running fine (according to top and snappy terminal responses). [URL]
I am getting very slow UI response in Lion. (iMac 27", 3 GHz, dual core i5 processor, 8 GB ram, 250 GB free on¬† HD). SmartReporter says disk is operating in spec (ie no alarms). Opening disk folder takes 5 seconds to get a spinning beach ball, with another 5 or more seconds to get the folder open. Also slow on directory scan during file opening dialogs. Even get the delay when opening USB drives.¬†
OS 10.7.3, with Apache running, and the usual¬† load of extensions operating. But what I find irritating is that Activity Monitor reports CPU at 25 %, HD occassionally spiking to 100%, but not often, and still I seem to get these unexplained delays. Not fun. Turned off 'disk sleep' in energy saver preferences. Seemed to help for a while. Now not. Reinstalled OS X twice from store and with a USB download stick. Get wierd errors on Console: "5/6/12 5:20:31.000 PM kernel: IOSurface: buffer allocation size is zero".¬†
Killing Safari/Flash via Activity Monitor makes a small amount of speed difference, but not much.Any comments? Suggestions? Is this a general issue with Lion? Are there any profiling S/W diagnostics that might suggest where the processor is spending its time?¬†

an update that requires a restart on the computer, and after I have completed that update, the computer runs slow. Even with 4GB of RAM and a 2.66GHz C2D Processor - Finder, Numbers, and some games run slow.
Many extensions on extensions.apple.com cannot be installed.However, extensions that I installed before, no problem, such as AdBlock, Bing, Echofon. Others, will not install, it will be stuck at installing. And Safari may lose response after a while. I initially noticed that if I try to install YouTube5 which I downloaded myself, Safari will immediately lose response.
- Reset Safari - Run OnyX - Repair disk permissions - Deleting all the extensions; extensions I installed before will install, others won't - Deleting Clicktoflash and Glims
I'm running 10.6.4 with the newest flash 10.1, and when I load a page on safari or firefox with a flash video on it on my iMac the scrolling on the page doesn't work and the video takes about 5 minutes before I can press play. I have tried running different versions or flash (uninstalling old ones and things) but nothing fixes it.
This is perhaps an expected result, but from the launch of iTunes (V10.6) in OSX (V10.7.3) until the beach ball stops spinng takes close to 5 minutes.†I have just under 20,000 tracks in iTunes.† Probably 95% are in iCloud.† I suspect that this is the culprit.† The track list loads within 30 seconds, but the spinning beach ball of death just keeps on chugging. I do not display album art.

I recently bought a Power Mac G5 with 3 20" cinema displays, each with their own video card. I've since stopped using one and it sped up some. But even with the most simple tasks, it is hella slow and freezes sometimes. If I just have Firefox and iTunes open, it runs slow and the fans kick in overdrive. The main video card is an ATI Radeon x800 with 256 RAM and the other is a 9200 with 128 RAM. how to free up my RAM and speed it up?
I've been monitoring the CPU temperatures on my 2 week old alu macbook frequently, and it always hovers at ~42 degrees celsius. However, today something odd happened, all of a sudden the computer was getting noticeable hotter (the fans remained off though), when I checked CPU temp it was up to 72 degrees. I checked with "Activity Monitor" and nothing was using up more than 2% CPU. Then I saw through iStatPro that system CPU usage was at 40%. What the hell? Its usually at 2-5%...i.e. always. After restarting, the system cpu usage was back down to 2% and the temperature slowly dropped back to its norm.
I have a MacBook, using iMac atm but my MacBook is running 50-60% system, 0.5-1.5 user, and i do not know why its using so much of my CPU... No programs are running except Activity Monitor... So I'm not sure whats going on, i have all the latest Airport, firmware and all that...
I just bought my first mac (2010 13 inch base model) and i was looking in Activity Monitor when i noticed that my free system memory is around 15-20mb. Is this normal? The only things i have running is chrome, itunes, and steam. Would these programs eat up memory? if this is a stupid question please forgive me!!!!
i need to return my iMac to service so it's time for me do a latest backup and my question, is there a way to do backup of whole disk but when restoring only the content without the system because this is a great opportunity to do a fresh install of snow leo.
My Mac is missing codes or something, all the software was up to date but I'm unable to view a lot of web content. Google programs won't let me sign in and Safari keeps shutting down. I'm unable to save files to the time machine or airport or a flash drive that's formated for mac. I finally gave up on saving my things and using the recovery disks that came with my computer I reinstalled the system. It took an hour for the disk to run and then I used the second disk to install the apps. However, when the computer rebooted all of my things are still there. MSN messenger for mac, divx, aim, and some other programs that I had installed seprately after purchasing the computer. I wanted factory settings. I told it to formate the hard drive.They might be what's causing my problems? Also, why does the delete button keep taking me off this board and I can't see what I'm typing it keeps scrolling off page!
In Lion, there is this insipid wobbling of the page's view (programmer terms, I know) when the page has no scroll bars (scrolling set to always on) and you use the magic mouse's center point to finger scroll up.¬†The "view" scrolls away from the top left corner to display nothing, then snaps back.¬†As I am a leftie and I EXPECT the scrolling to STOP AT THE END OF THE SCROLL REGION, how do I burn this setting to NEVER EVER DO THIS.¬†It is distracting and useless and irritating.¬†this even happens witn an empty page.¬†I never ever want my UIScrollView's content to allow the content's view pane to drag away form the edges that contain it.¬†This didn't happen in Snow Leopard and my Mac with a 27 inch screen and a 17 inch screen is not an iOS device.Is there a pList setting for Safari that will allow the UIScrollView.bounces to = 0 or UIScrollView.elasticty = 0?¬†Can I edit the Framework header in /Library/Frameworks to set the default to NEVER for all epplications?¬† I can't use Lion with this is happening all the time I mistakenly trigger a scroll with my middle finger using the Magic mouse.¬† ¬†
I'm sure you've all read about the Firefox memory leak brouhaha. Firefox 1.5+ is supposed to suck down memory like there is no tomorrow.
Someone made this challenge:
"If you keep opening tabs in Firefox ÔŅĹ say, more than 10 or 15 ÔŅĹ the browser starts to slow to a crawl. See how many tabs you can open, but participate at your own risk! Oh, and uh... be sure to save all of your work first."
Well I ran that test. I opened 33 tabs in FF 1.5.01 on my iBook (see sig). FF doesn't bat an eyelash, no slowdown whatsoever.
Right now my processors are pinned at 99 and 100% and a look at Activity Monitor shows 6 processes, relating to my safari boot page.. you know with the small web shot pages... Strange thing is that the temp and fans are not going up... The processes are called Safari Webpage Preview.
