Snow Leopard Memory Hog

I have a late 2008 Unibody 13" Macbook 2ghz w/ 2GB of memory. I took a screen shot of the Activity Monitor before installing the update and I had 1.4GB of free memory and now I have only 769MB free. Is it just me or that is what the new OS use in memory. Virtually is sucking up all the memory that I have.

Any suggestions? or is everyone experiencing an significant increase of memory usage?.

Thanks.

MacBook Unibody 5,1, Mac OS X (10.5.6), Snow Leopard Memory Hog usage

hahah I went to try the help tab and crashed. I am using Firefox 3.5.2. The older versions did hog memory, but before SL and having 3.5.2 everything was fine. Firefox was returning the memory that was not using.

After SL, Firefox uses a lot of memory as well as core process as Finder, kernel_task, windowsserver and dashboard client. They didn't use that much in the past.

It is insane, I am just surfing the web and I have only 500mb free of memory.

You're ready to quit after a single day? SL is brand-new, Firefox is no doubt working on the Help problem, and there don't seem to be scads of folks chiming-in here with the same problem. Have you told Firefox about this? Re-loaded it? Re-loaded SL?

GFNG,

Why are you so concerned about free memory? The real question is: Are you swapping to disk???

Open Activity Monitor. Note what is listed for "page-ins" and "page-outs." Please post what you find here.

Otherwise, use the thing normally, and do not stress out over what is going on with your memory. Snow Leopard will use it in the most efficient manner possible, whether you worry about it or not. Do whatever it is that you do with your computer, and quit worrying.

Right. You know, I was making that same argument back when iTunes for Windows came out and everyone got all fussy about the fact that iTunes wanted to organize the files in a way that made sense to it. "My music" they said. "This stupid program messed up all my hard work" they wailed.

But...when you press play in iTunes, does it not play the music? "Yes, but that's not the point, I spend years of my life creating a file system and now it's ruined" they moaned.

So...stop organizing files and start listening to music. I was not very popular with that. I hope you are met with more optimism. 😉

And you are right, so very many of these threads over the past two days are folks obsessing about some number somewhere that truly means not so much unless the computer is no longer doing what it does so well. This too shall pass, then there will be 10.6.0.1 and there will again be the cry of "Apple broke my computer!"

Ah, memory. er, memories.

I have already told firefox. But is not firefox the main problem. The SL services are the one that are causing memory hog. I had a feeling before I updated, so I did a test of before and after update. Finder, kernel_task and WindowsServer are using twice of the memory and then they do not release them back, they keep taking more and more and I have to restart to reset it.

mmmm I may try to reload SL.

My bad, I did not know that I needed to be so specific. My concern about free memory is not because I want to have nice numbers in the Free memory section. This is not the stock exchange. This issue is slowing my computer and causing overheat.

I do multi task, I need to work in word, find stuff in firefox and even use photoshop to fix a picture. The point is that Apple was advertising this OS as faster, refined and better but did not mention that will use so much memory so I will had wight the pro and cons of the upgrade.

About the iTunes comment. You should be able to do with your computer whatever you are comfortable doing. If you want to make list and you spent time doing those list, the operative system must adapt to the users. You should be able to have certain freedom to customize the system so it works better for you. That is why I chose to get a Mac instead of windows.

There may be things that are not annoying for you, but it could annoy others and having the option to do so, that is why apple is a step ahead of others.

In windows you must adapt to whatever MS want you to adapt. Apple was different, they create things thinking about the user and they adapt the software to our use.

I just think, that this update was launched soon before checking all the side effects.

Free memory doesn't much matter if the computer is responding correctly.

My computer rarely has more than 90MB free at any given time (I've only got 1GB of RAM here, and love to have multiple apps and other goodies active). It does lag on occasion, but I clear that up by shutting down my main memory hog (Firefox) and reopening.

On to your issue!

You mentioned in your latest post that your computer is slow. In what ways is it slow--be specific! Is web browsing slow? Are applications slow to launch and/or respond?

Your computer shouldn't overheat--if it does, it WILL shut down. The fan(s) may kick in, but that's not necessarily cause for concern.

Another thing to keep in mind (if I've understood other threads correctly):

With Snow Leopard, the amount of RAM used for the video card is deducted from the total memory & the user will NOT see this RAM included in the pie chart for Activity Monitor.
