Attached image Chart from js workweek — 
Much like bug 852187, and as discussed at the 2013 JS Workweek, it would be very useful and beneficial if we could reduce the cost of executing postMessage(object), particularly for large objects.

The attached chart shows a test run from http://dblohm7.ca/Bugzilla-832664/. It looks like IE10 must be using some kind of zero-copy implementation given the large gap in performance between worker->main postMessage and JSON serialization.
