Summary Large WebKit memory footprint(?)

Webkit is leaking memory pretty badly. I have two Mac G4/867DP-MDD's. One is loaded with 2 gigs and the other 1.5 gigs of ram. I start surfing and activity viewer shows memory 75% free. After 15 - 20 minutes, only 10-15 mb of ram is left free. Memory leaks galore! I know it's hard for web apps to be memory efficient due to all kinds of stuff loaded on sites. I'm mainly surfing to text based sites. Looking at very few image/video sites. See what you can do to optimize ram usage. WebKit is a great product. I wouldn't use anything else! With Respect, Donnie Dixon. Running OS-X 10.4.11 with latest WebKit build.

What is the RSIZE of your Safari process? What version of WebKit are you using? There are a variety of reasons why the memory usage would grow, but it does not necessarily indicate that there is a leak.

From email: > Thanks for your reply. I am not a programmer. I'm a WebKit enthisiast. > WebKit version is 29907. Memory creep happens under all versions I have > used over the past two years.. Safari RSIZE varies between 100 - 200 mb. > VSIZE is from to 350 - 500 mb. Memory stays consistent using top, but > I see that it's the only app that creeps higher and higher so that free > space is used up to the bare minimum.

I don't think that 100 - 200MB is overly large. A bunch of things are cached in memory to improve performance, and the memory figures you mention are consistent with what I would expect given the cache sizes used with 1.5 - 2GB of RAM. I wouldn't expect it to negatively impact the performance of your machine either, as if the memory is unused it would simply be paged out when the system is low on memory. > I'm just curious, what language is safari/webkit coded in? C++ and Objective-C.
