When I'm try open www.hexblog.com page on any webkit-gtk www-client it take a lot of cpu and memory usage. This is simple page, without any unusual JScripts
I can't see this problem with current trunk on Safari. If this is a WebKit problem, it must be GTK related. Please provie more informations: Did you try this on an other machine too? Which OS do you use? Which processor? What is the exact version do you use? Did you compile it yourself?
Reffered from http://luakit.org/issues/70 This is only webkit-gtk issue I'm using webkit-gtk-1.2.6 from gentoo linux x86 Intel-based system Yes. i'm compiled this myself. But this bug confirmed on another machines. Also as you can see maintainer from luakit also confirmed this.
I believe this is a duplicate of an old bug resulting in very slow box shadows. If possible, can you try to reproduce this on a recent build of WebKitGTK+. If you can, feel free to reopen. Thanks for reporting! *** This bug has been marked as a duplicate of bug 39582 ***
