I am on a MacBook with 10.7.5, 8GB of RAM and with 7 (seven) Safari 6.02 windows open (nothing special going on - one small .pdf, nyt.com, a few simple sites) Safari Web Content is taking 5 and I have 23mb of free RAM. Safari is taking up 65% of physical RAM for seven pages, and that does not include the 'Safari' process. Beyond frustrating that this persists. How can Apple not cure this issue, or at least explain it if not solvable?

Well, here's the problem: performance is terrible when the system is out of free RAM!
I can't count the number of times my system has slowed to a crawl, and quitting and re-launching Safari cured it.

G Robert Lewis, greetings: So long as there is Free space and Inactive RAM available, RAM as such should not be responsible for a system slowdown. I would be looking elsewhere for the 'bottleneck'.

I have enabled the World Leaks: Check on All Builds option in Safari's Debug menu. Every time I close all Safari's windows (without quitting the program) I get a message like this:
So: if all is well, why is Safari asking me to file bug reports, and why is my system so unresponsive (and fixed simply by re-launching Safari)?

G Robert Lewis, greetings: May I suggest that you start a new post regarding your issue. I think your problem justifies that approach and I suspect that may elicit more responses from the forum community.

I found in Activity monitor that Safari was using 66% of my ram. i also have 2GB. I thought this was excessive. I looked into a number of things. Then I went to Safari preferences and then to Privacy. I checked the Ask Web Sites Not To Track Me box and on Limit wecsite access to location services I checked the Deny with out Prompting Box. Checked Activity Monitor again and Safari System Memory use had dropped to 4%. After that I also disabled over 1000 cookies. Everything seems to be better and I have lots more System Memory available and I am not getting the dreaded beach ball just opening normal applications. Has anyone else tried this or know of any reason why it would be a problem to check those two boxes.

I have 16 GB RAM. I closed all windows in Safari. The Swap file in Activity Monitor grew from over 16Gb to over 24GB in less than 10 minutes. Safari, with no windows open, is using 13Gb. My 2012 Macbook Pro is running very slowly. There is something wrong with Safari.
(My 13" Macbook Pro also shuts down about once a day for no reason as does my 15" Macbook Pro).

Peronsally I think there is a problem with Safari, that has been ongoing and is making my MacBook and iMac both often unusable more and more and more. It is mindboggling that there has not been a fix for this. Safari web content alone on both my machines typically grows to 6GB out of 8GB of ram, and then the machines experience the requisite performance hits. Always at time when it is critical to get work done.

My swapfile usage has grown to over 56GB since my post at 1.24pm. That's about 32Gb extra in 44 minutes. There seem to be problems with all their latest releases of Macbook Pro that were not there with Snow Leopard and Macbook Unibody.

Maybe if Apple is inundated with bug reports they'll give this issue some attention.
I recommend everybody do this:
First, enable Safari's Debug menu. Here's how:
- Quit Safari
- Launch the Terminal and enter the following command:
defaults write com.apple.Safari IncludeInternalDebugMenu 1
- Relaunch Safari
Then go to the Debug menu and select World Leaks: Check on All Builds.
If your system is like mine, every time you close all of Safari's windows it will give you an error message and ask you to file a bug report at bugreport.apple.com (you need an Apple ID). Do so. And cross your fingers.
Hmm. The fact that Safari even has a debug menu must mean that it's not the most solid program.
(As usual, if you want to disable the Debug menu for any reason, use the same command as above but change the "1" to a "0". But I don't think it can do any harm to leave it enabled.)

I am running Lion on a mac pro with 15gb ram. Safari was giving me the same problem (using crazy amount of ram). I switched to Firefox which was worse as I didn't install click to flash which I had in Safari. They both were hogging 8gb+ of ram. I am trying chrome now... In SL, the only time I maxed my ram and started paging out to VM was when using FCPX with all my regular apps open. Does Mountain Lion fix this? I believe I read other threads where ML users have the same issue. A lot of other people point to Safari 5 as the problem. I am wondering if FF shares webkit stuff with safari or if is just independently also written so poorly as a memory leach.
