I hate to be "that guy," but loading this page reproducibly spikes the CPU usage of a "google chrome helper" to 36% of my CPU. When I kill the helper process, I get the "Aw Snap!" message in the mixpanel tab, meaning yes, indeed, it was this page...
Usually google helper is a martyr for "a plugin." Curious to figure out which plugin is having a hard time or maybe it's something else? We are happy to fix this with more info!
