I don't see any benchmarks showing this as "faster." Seems like a pretty serious claim.
From the Firebase JavaScript SDK, I can do one thousand individual gets with a 3.4k payload at 1-2ms each. http://jsfiddle.net/katowulf/8wkon62c/
Mileage varies, of course, but I'd love to see a benchmark I can run side by side that can beat those numbers. I can't even get close with a simple GET, which returns in 86ms.
