           Summary: AX: iOS: using AXAttributeCacheEnabler is too slow for
                    every accessibilityElementAtIndex:
           Product: WebKit

        OS/Version: All

          Severity: Normal
          Priority: P2
         Component: Accessibility

On iOS, the attribute cache enabler is being used on every access to elementAtIndex. 
Sample shows that we're spending a lot of time creating and tearing down these objects. 

I think we need to provide the ability to enable and disable caching at a higher, more informed level, so that we can cut down on these costs.
