Gallery slideshow settings: editable somehow?

I’m using the slideshow mode for one of my galleries: http://i.imgur.com/6cir8vH.png

Can I configure the JS settings for this slideshow somehow? Specifically, I want my slides to cycle through faster than the default.

Data attributes in the output? Custom JS params/function? Is there anything I can do to speed up the slides?
