And that aligns with previous rules of thumb I&amp;#x27;ve used for mobile UX -- you generally want things to be &amp;lt; 100ms, and ideally &amp;lt; 50ms. If something results from user interaction the bar is much closer to the 50ms side of the range.</text><parent_chain><item><author>ch4s3</author><text>&amp;gt;  the UX is fairly laggy&lt;p&gt;I don&amp;#x27;t really find that to be the case.
