But some of there method has only a few overrides other than one for tree traversal its self. Such methods includes insertedIntoDocument, insertedIntoTree, removedFromDocument, removedFromTree, willRemove, attach and detach. It looks possible to de-virtualize (and even inline) these method by - pull tree traversal out from ContainerNode/Element - Employ a node flags to declare the existence of overrides - inline methods for major DOM classes (that include Text and Element) Since a large part of DOM nodes don't have node-specific overrides other than major classes above, These inlining will gain certain performance win. I'll start from easier ones and see how it work. 1891918 1 ahmad.saleem792 2022-08-17 04:34:34 -0700 rniwa@webkit.org - All dependent bugs are fixed, is something separately needed for this META bug? Appreciate your input. Thanks! 1892017 2 rniwa 2022-08-17 12:38:24 -0700 Yeah, this is done.
