On my first attempt, I noticed 8 Major GCs: https://cloud.githubusercontent.com/assets/297678/15036715/f41ea4d4-1247-11e6-8823-f153c3c1b7bb.png On second attempt, no Major GCs: https://cloud.githubusercontent.com/assets/297678/15036788/c066483a-1248-11e6-970b-3f9d20710bbc.png I wonder why. I'm in Chrome 50. So, the second attempt looks good. I'm not sure why the first is so different. I tried it a few times, but I only got that Major GC zig-zag the first time. Thanks for pointing out Set!
