Going to the transition page using jQuery using the velocity.js function

Question

My jQuery app for high-capacity mobile applications uses transitions to change the page using gestures, for example:

$(":mobile-pagecontainer").pagecontainer("change", "#mynewpage", {transition: "slide"});

The performances are really too slow, so I thought about using speed.js. I know how to use it to animate an element, but I can’t understand how to use it in the page container change event, and in general for all the transitions included in the widget event (such pop-ups, page changes, etc.)
