------------------------------------------------------------
I'm starting to feel around the edges with 2 of my local machines and simple
benchmarking.
I've found two fairly concerning things so far:
* I can't seem to saturate any key resource.
* The VersionInfo bucket size appears to be a large bottleneck with replication
(we lock on this bucket in DistributedUpdateProcessor for the entire document
add).
I've attached a PDF record of my runs that I'm keeping.

> holes.
> Note: A common report is that adding any replication is very slow.
