Safari's Memory Usage

Does anyone have any idea why Safari uses so much memory after a few hours and lots of page loading? I've got people telling me it's using 106 megs, 116megs, 78megs and 64megs (I've asked 4 different people).

Is there anyway to prevent such horrid usage? It leads to massive paging out very quickly if you are on an iBook with max RAM.

If I could just get ahold of Dave Hyatt and ask him.

Digg This!

what happens if you flush the cache?

Dave Hyatt has a weblog for bugs and questions at http://weblogs.mozillazine.org/hyatt/

But he takes comments only on his personal blog at: http://weblogs.mozillazine.org/dave/

However, you see how long it's been since he updated...

I've found that it starts eating up resources if I'm downloading a large file or have downloaded a lot with Safari. The only solution is to relaunch it.

Dave's personal blog has moved. Not that difficult to find though... (clue: an organisation of hyatts)

Have you logged this with Apple?

I've had mine open less than an hour at this point, and it's up to 95real/250virtual.

Whenever I look at the Activity monitor, every page I go to adds some more data to the memory for Safari ( I had it up to 225mb!). It adds up the more pages you visit. I think it sucks.

I just noticed the same thing. Page size is 433MB and RAM is 93MB. I had it up to 120 yesterday. I cleared the cache with activity monitor tunning and watched it drop by half. Still was large. I think there needs to be a pref to set the size of RAM cache. I don't care if it dumps a page that I viewed 2 hours ago.l

I just checked my girlfriend's Powerbook and Safari had 1.2Gb of virtual memory (and 140Mb physical) - no wonder it was going *so* slowly!

It's definately leaking memory. Here's the output from top:. Virutal memory 2.98G!

i tend to just put my computer to sleep without shutting down, and safari is normally something i just leave open. this morning my computer was going slow, i checked the memory usage, and safari was using over 500MB of real memory!!! i quit it, and then all was well again.

well, i figured out something better, by minimizing the safari browser, u get the temp reducing of memory usage to quite a lot!
