New Google Maps is now rolling out to everyone's desktops

Looks like Google is rolling this out to everyone. Personally, I'm not a huge fan of the design, but that's entirely subjective on my part and I recognize that.

HOWEVER, what is not subjective is how slow it is and how often it causes my browser to hang (judging from the comments on this article, I'm not the only one who has experienced this...). Has anyone dug into it to see what it is that is causing this version of maps to be so resource-intensive?
