profiling the painting that happens on a window update event on mac, nsFrameImageLoader::IsSameImageRequest() is 5% of the total paint time. thought i'd filed this already, but guess not.
You'll find that the parent of this call is nsPresContext::StartLoadImage() (bug 64438).
Reassigning to Attinasi.
I think that once the dependency is fixed, this won't be a problem. The code for IsSameImageRequest is not that bad.
i should probably take this since nsFrameImageLoader is going away.
Stuart, feel free to take it, but please point me to more info on the frameImageloader's impending demise... Thanks.
Over to pavlov, as he suggested (Comments From Stuart Parmenter 2001-02-20 11:40)
nsFrameImageLoader isn't used anymore.
Marking verified per last comments.
