I’m currently in a library using their net access while out of town and the connection is pretty slow.
With that said I noticed that the EE homepage showcase slider shows all the images while loading versus just three. They pop in to place at the last second of the load process.
I think this could probably be remedied by adding overflow:hidden to the #showcase div.
Not sure if it matters or not based on your user base though, I thought I would throw it out there for whatever it’s worth.
