Safari 5.0.4 - memory hog

Is it just me, or is Safari eating up 25% more RAM durning long sessions since the update to 5.0.4?

In my job (QA Engineer), I have Safari, FF and Chrome open all day on a large number of pages. By the end of each day, Safari is taking up 3-4 times more RAM than the other browsers, and about 25% more RAM than it did before 5.0.4. Even after closing every tab/window. The memory leaks are enormous.

Suggestions, anyone?

Macbook Pro 13"/2.26 GHz, Mac OS X (10.6.7)

Hi


a couple of times my system has virtually stopped (screen save freezes), no obvious culprit, however Safai was running monitoring my router.


So I observed the memory usage, started at 134Mb, every refresh of the same page, no other pages open, up went the memory, never dropping until i shut the page.


So perhaps there is a problem, can you confirm this behaviour?


This is on a mac mini with 1G of RAM

No, not just you. What I've noted is that Inactive memory accumulates, and Free memory decreases, until the 2GB of RAM on my iMac G5 is essentially 100% used. At the same time the number of Page Outs begins increasing and catching up with Page Ins. Safari becomes increasingly sluggish. It may be necessary to Quit Safari several times a day as a workaround. This problem did not exist at some point, maybe it began with Safari 5? (There was a change in how caches were handled at some point ... the user's Caches folder ~/Library/Caches used to contain, for instance, Safari's actual cache, now you'll see it contains a folder com.apple.Safari that includes Cache.db which is an application not the actual content.)

Sorry if I'm in error; when I tried to open it I got a message that it may be an application that was downloaded from the internet. Its icon is like a document though. (I've had a different problem where deleted cookies would reappear after clearing Safari's cache unless I physically deleted the Safari cache after quitting Safari but before relaunching it - haven't checked this on 5.0.5 yet - so I concluded that data was actually be stored elsewhere.)

I had the same issue. I've actually had my system totally freeze multiple times and was debating if Word or Safari were to blame. I had downloaded the beta of the new version of flash thinking maybe that was it. Removed. Still problems. My poor Mac innards start screaming sometimes when using Safari after the update.


4.0.5 just released via software update. It does seem... better... but after awhile it gets slow and crawls as well with the same problems, but not system freezes yet. (Crossing fingers.) Having to totally power off your system is just not acceptable.


To what Mr. Cat said, quitting Safari doesn't solve the issue either.
