> Reproduction steps:
> 1. Open https://bugs.webkit.org/attachment.cgi?id=142634 (Caution: 5MB!)
> 2. Instrument the Web Process while WebKit opens it
> 
> Observe that we spend 19.5% of time in HTMLTextAreaElement::defaultValue() inside HTMLTextAreaElement::childrenChanged, which in turn is called by ContainerNode::parserAddChild (18.5%).

Did you link to the wrong page? There's no textareas on that page, just plain text.
