RE: Hive Node Setup for the Smart, the Dumb, and the Lazy.

For now I have results for first 50M blocks:

50M blocks	Real time	last 100k real time	last 100k cpu time	parallel speedup
Replay	`6:32:45`	`43.466s`	`61.132s`	`x1.4064`
Replay + Validate	`11:03:00`	`84.337s`	`395.575s`	`x4.6904`
Resync	`14:31:33`	`103.266s`	`182.288s`	`x1.7652`

I just counted last 100k block times (cpu / real) so it's not a great measurement. I can have better numbers once I complete those runs. But it seems that replay with validation can somehow make a better use of multiple threads than validation during resync.
