           Summary: AX: Reduce the IPC traffic when calling

           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

Currently with accessibility enabled, the web process constantly sends IPC messages to the UI process asking for a converted element frame. This could lead to a bad performance when there are thousands of elements on the page. 

We should be able to cache enough information on the web process during page load or window movement, so that we are able to save lots of effort communicating back and forth.
