Hi All, I'm posting this question on the dev list because it's probably a question that can be best answered by developers who know a lot about the inner workings of webkit. I'm testing various webkit ports on fedora and have observed the same cpu usage behavior across all ports. The pcpu number from ps on the webkit browser process always tappers down slowly after each loadFinished signal has been fired, even if it's a page that does not have any ajax/javascript activities after the page is done loading. It sometimes takes a few minutes for the cpu number to go back down to zero. My question is what does webkit do after the page is done loading that's taking up CPU? Running the browser through strace shows me that a lot of times clock_gettime is called continuously after the page has loaded, and no more request comes in. However even when these clock_gettime calls subside, I still see CPU number great than zero. Any pointers would be helpful or even just sections of the code to look at. I'm trying to use webkit in a resource constrained environment so every little bit of cpu gain counts.
