I mentioned this briefly in the "CPU load to high" thread.

When I start Qt, it uses about 30-35k in memory. Pretty soon, the number starts cascading higher. Occassionally it settles back down, but it usually ends up using more memory than Firefox! Earlier tonight I had 2 tabs open, one on the Wizards.com forums and one on cracked.com, and the browser usage was hovering somewhere around 150k. To compound the problem, the momry usage doesn't seem to want to deflate if I close a tab or two. If I have a single tab open, open another tab, then close one of them, the memory usage stays consistent.  Any thoughts/ideas/suggestions? This wouldn't be a problem on my home computer, but I'm on a work machine that is an absolute dinosaur.

Perhaps QtWeb suffers from the same kind of memory problems Firefox does?

Or maybe someone forgot to do a memfree() somewhere...

Yes, unfortunatelly problem with memory usage exists in Qt 4.5.0 adaptation of WebKit implemenation

I've found couple places, for example, in  FontCacheQt.cpp, which is not fully implemented.
However to dig through all 85MB of source code is too much.

Hopefully, in next releases of Qt,  developers will address this issue...

Hi

Fully rewritten Nokia's Qt 4.5.0 implementation of FontCache which was just not fully implemented.

QtWeb 2.0 build 051 contains custom implementation of FontCache.

Now browser has much less memory leaks

Awesome job, Alex, you're the man. QtWeb version is 2.0 (build 051) now runs smoothly with my laptop thanks to this new build.

Wow...wonderful. Yeh, it works great now.
