<p>The new accessibility javascript in the Appearance > Menus panel in WordPress 3.6 can significantly slow the page load speed when using a large number of menu items (> 50).  This plugin defers the accessibility processing to eliminate the scripting bottleneck and allow the Appearance > Menus screen to run much faster and more responsively.</p>

<p>This solution is fairly rough.  Hopefully we can develop a robust solution that can eventually become part of the core.  Pull requests through GitHub are welcome.</p>
