      Before I try 1.7, it's worth noting there's a sometimes-STW bug fix in 1.6.2. Here's what 1.6 -> 1.6.3 looks like.pic.twitter.com/dsPrTqEyGF

          1.9rc2 canary: sub-millisecond pause time GC (18GB heap). Same as 1.8.3. If you're not on 1.8.3, upgrade or try 1.9rc2.pic.twitter.com/RX4CPOcxaW

          total pause time vs 1.7? I'm curious how much - if any - GC throughput suffers for lower pauses.
